OBJECTIVES
to learn allaspect of raising a free range
chicken for their meats and eggs. Then to
develop a business plan which will show them
if they can make money out of a free range
chicken enterprise operation in their region
under the present condition
5.
Introduction
Investing in freerange chicken is non sense unless it
can be sustained; that is it can survive over a long a
term. Therefore, it is very important to learn or have a
knowledge first be answered honestly before the farmer
decides to launch into a chicken enterprise in which you
will have to invest time and precious money. In short,
“knowledge, practice and experience is your input
to a better output.”
6.
Some of theimportant reason that relate particularly to the health of
your children.
Chicken meat and eggs contains special proteins that:
Allow your children to grow strong
Allow their brain to develop so that they will be clever at school
Allow pregnant mothers to produce healthy babies and to produce healthy
babies and to breast feed them.
Allow children to be healthy and not to catch cold and coughs.
Eggs and meat also contains vitamins and minerals that are essential in your
diet.
Therefore, if you decide to venture in free range chicken always remember
to key some meat and eggs for your own family to eat.
7.
What is freerange chicken?
Free range chicken is refers to food from chickens, like its meat and eggs that are
produced from chickens that have access to outdoor spaces and who have free
access to graze or forage for food. However, although the term “ free
range” ,brings to mind wide open spaces with animals living in nature, eating
natural foods and soaking in the sunlight, it is very important for producers to
ensure that it require originally-raised and certified organic standards.
Another important positive with starting out with chicks is that they will grow up
to become familiar and comfortable with the people around them. The obvious
downside with chicks is that they will require a lot of care, if they are to reach
production age.
The producer should always expect some mortality ranging 2 to 5% from day 1 to
harvest. The mortality rate will depend on the goodness of your product.
8.
Housing
Consideration in planningthe house structure
Type of stock and Production Capacity
The building and fixtures should the purpose for
which the birds are raised. Layers and broiler differ in their
requirements. Likewise, there should be sufficient for the
desired number of birds to be kept.
9.
Environmental Factors
Birds mustbe protected from poor ventilation and extremes
in temperature. When the land dimension allows it, the poultry
houses should be constructed with their length parallel to the wind
direction. This setup will expose to the wind only the Southern or
the Northernmost portion of the houses. If it were the other way
around, that is, the length of the house facing south, all the pens
with the birds therein would be exposed to draft and heavy rain
during typhoons and bad weather. Discarded feed sacks when
available, can be utilized as wind and sun breakers. Planting trees
will also serve as wind breaks.
10.
Sanitary Provisions inthe Poultry House
In planning the construction, due consideration should be
given to facilitate cleaning of the poultry house. Thus, in the case of
brooders, the floors, sides and partitions should be detachable. This
will permit their removal for thorough cleaning and disinfection
after every batch. There should have a good water drainage from
the house site. Due consideration should be given to the aspect of
poultry disease prevention and control. When there is ample land
area, the breeding, growing and laying houses should be reasonably
spaced from one another as a health safety measure.
11.
Provision for EasyExpansion Consider future expansion plans.
The building that are to be constructed should consider the setting
up of additional new houses that may be needed later.
Economy of Construction
Poultry houses need not be very expensive to construct. There are
many locally available cheap materials which are very common to
poultry raisers like bamboo, coconut trunks, cogon, nipa and rattan.
The rule is to use local materials which are very common to poultry
raisers like bamboo, coconut trunks, cogon, nipa and rattan. The rule
is to use local materials that are readily available.
12.
Pen’s Classification
Brooding Pen
Abrooding pen must be a safe, dry, uniformly warm, draft-free place where
chicks spend the first weeks of their lives. Brooder lamps come in two basic
types, gas and electric.
13.
Meat Production Pen
Thebuilding and fixtures should the purpose for which the
birds are raised. There should be sufficient for the desired
number of birds to be kept.
In free range space requirements:
Broilers
a. Day-old to 3 weeks 0.3 sq. ft /chicks
b. 3 weeks to 4 weeks 0.5 sq. ft./chicks
c. 5 weeks to near market age 1.0 sq. ft./bird
15.
Layers Production Pen
Thelaying house should be built according to local climatic conditions and the
farmer’s finances. A good house protects laying birds from theft, predation,
direct sunlight, rain, excessive wind, heat and cold, as well as sudden changes in
temperature and excessive dust. If the climate is hot and humid, for example,
the use of an open house construction will enable ventilation. The inside of the
house should be arranged so that it requires minimum labour and time to care
for the birds.
The following space requirements may serve as guide:
Layers
a. Day-old to four weeks 15 sq.cm./chick
b. Four to eight weeks 30 sq.cm./thick
c. Nine weeks to laying age 50-60 sq.cm/bird
Beddings
Beddings in broodingis newspaper and it is changed daily. After 21 days
chickens are transferred to another pens if it is for meat type or for layer. For
meat type and layers the bedding contains 7 sacks rice hull, 1 bag carbonized
rice hull and IMO2 or EMAS.
Lighting Equipment
It enablechickens to let them easily find the feeds and water.
Incandescent Bulbs.
Traditional bulb choice
in poultry farms.
Inefficient because
power is released as
heat. Lifespan =>1,000
hours or approximately
two months if lit 16
hours/day.
22.
Watering Equipment
Give yourbirds clean and fresh water. You can make your own drinkers or buy
them. They must be adjusted to the correct height so that birds can drink
easily. It should be elevated as chicks grow for both cleanliness and drinking
efficiency. For this reason, the water lip should be higher than the feeder
trough.
Recommended Minimum Watering Space Requirements
a. Day-old to 4 weeks 0.5 cm./bird or two 1-gal drinking fountains/100 birds.
b. 4 weeks to 8 weeks 0.6 to 1 cm./bird or two 2-gal drinking fountains/100 birds.
c. 9 weeks to near laying age 1 to 2 cm./bird or four 2-gal drinking fountains/100 birds.
d. Layers 2 to 2.5 cm/bird or six 2-gal drinking fountains/100 birds.
23.
Pan and JarType Drinker. Circular in Nature. Have two
compartments i.) jar for filling water, ii.) pan for delivering water.
24.
Water Basins madeof plastic/wood with grill. Water basins
made of plastic are of different diameters (10”,12”,14” and
16”).A separate grill is available to prevent the entry of birds
inside the water.
25.
Feeding equipment
Chickens musthave continual access to feed in properly-adjusted
feeders, otherwise they will not grow or lay well. They may be
conventional, semi-automatic of various designs and shapes and
made up of wood, bamboo, metal and plastic. Feeders must always
have a lid to stop birds from entering the feeder.
Recommended Minimum Feeding Space Requirements:
a. Day-old to 4 weeks 2.5 to 5 cm bird
b. 4 weeks to 8 weeks 5 to 6.5 cm./bird
c. 9 weeks to near laying age 7.5 to 9 cm./bird
d. Layers 10 cm. /bird
26.
Linear Feeder. Differentsizes of linear feeder with guards are
available. It is usually made of galvanized iron. However it can as
well as be made out of any locally available material like wood,
bamboo and plastic.
Spring Balance orWeighing
Scale. An inexpensive spring
balance for weighing birds,
feeds, eggs and other things,
you will find to be very
useful.
29.
Portable Catching Panels
Thisis usually made of either
bamboo, wood or wire frames.
This device comes in handy
during vaccination.
30.
SYSTEMS
Brooding
This is aterm which means, keeping chicks warm and comfortable. When your baby
chicks arrive they will need special care.
Things to do:
Start with 21-day old Dominant Asia which are already hardy and with lower mortality.
1. De-stress the chicks if delivered to your farm by giving them water to drink. Add brown sugar
to the water at the rate of one percent (about two tablespoons per gallon of water). The
sugared water will rehydrate the chicks faster. Sugared water can be altered with water with
electrolytes and should be given within two hours from discharge into their brooding pens.
2. After two hours from arrival, the chicks should have eaten and drunk.
3. The brooding area should have been disinfected. Rice hull, wood shavings, or straw make a
good litter. It should be level to avoid excessive stress on the chicks.
31.
4. The heatersor brooders have to be lighted at least two
hours before the chicks arrive.
5. Monitor the temperatures of the room/ building before
the arrival of the chicks.
6. In the first two weeks, protect the chicks from extreme
hot/cold condition. Brood them under the right
temperature (38 ͦC) at the edge of the brooder and above
28 ͦC in the living area during the first three days.
7. Thermometers in different parts of the building should be
used to control the temperature before the animals arrive.

Feeding
Aside from housing,feed accounts for 70% of the cost of
raising chickens. Some knowledge of the nutrient requirements for
chickens and applicable feedstuffs is needed before producers should try
mixing their own chicken feeds. Grains and other feeds ingredient need
to be milled and mixed to an exact formulation, and are best pelletized
for efficient feeding.
34.
AGE VACCINATION ANDHEALTH SUPPLEMENT PROGRAM
1 Note: On the arrival of the chicks, wait until two hours before giving them
something to eat and drink. After two hours, give them bamboo leaves and
brown rice supplement then electrolyte for stress reliever.

Feeding and waterrequirement
1. When raising 100 chickens, the drinkers required by the growing chickens will
be 10 basins distributed in the house.
2. They will also need 10 feeders. The house should be lighted 16 hours a day to
encourage them to eat more.
3. Give the chickens adequate feed according to their daily requirements.
4. To condition the chickens to easily find their feeds on the first day, use egg
trays, newspaper, or flat feeding trays. By the second day, it will be easy to
introduce the chick feeders for the birds.
5. Put feeds into the feeders 3-4 times daily to eat and minimize wastage. Never
throw stale or rancid feeds into the litter for this will cause more problems for
the birds.
6. Give quality feeds to avoid nutritional problem.
40.
7. Try notto incorporate antibiotics and other artificial growth promotants so
as not to affect its taste.
8. A formulation of 60-70% ground yellow corn and 30-40% soybean meal then
add 1-2% vitamin-mineral premixes.
9. One-part molasses and three parts water as wetting agent for the feeds
makes the bird eat more and grow faster. The wetting agent is very small – just
about 1% of the ration.
41.
Management
Feeding Management
Meat type
Broilercommercial rations are fed to the birds during the first 5 weeks and from
then on are replaced by the broiler-finisher ration.
All purpose of straight broiler ration is fed from the start to the marketing age of
eight weeks.
Commercial broiler feeds contain additives considered to be growth promoting
substances. Feed additives make the production of broiler profitable and help
broiler farmers control diseases. Purchase feeds from feed dealers nearest your
place.
42.
Layer/egg type
Starter mashis given to chicks from day old to 8-10 weeks old.
Growing mash is given to birds aged 8-10 weeks until they are 5 months or when the egg
production reaches 10 percent. This mash promotes pullet growth at a rate that is just right to
allow the bird to develop its body and internal organs so that it will start to lay at the right time.
The bird should not be allowed to get fat during the growing period because this causes poor
egg production and high mortality among layers. A good way of preventing fatness among the
pullets is to restrict their feed to 85 percent of normal consumption when they are 18-16 weeks
old then full fed them at 17-20 weeks of age.
Laying mash is given to pullets when they are about to lay (10 percent or until the layers are
replaced) or when they reach 19 weeks of age.
Wetting the mash or instituting wet mash-feeding at noon during hot days will increase appetite
of the birds.
Adopt a regular system of feeding because chickens resent abrupt changes in feeding habits
which gets reflected in their performance, especially on egg production.

Health and Biosecurityof your Chickens
Two major sources of disease:
First, diet if not correctly formulated can result in the bird getting a
metabolic disease due to a nutrient deficiency (vitamins or minerals) in the diet.
Second, disease that are caused by minute organisms called bacteria and
viruses. It is often necessary to treat the chicks as soon as they hatch with a
vaccine which allows them to resist the disease if it occurs. This is normally done
at the hatchery. Newcastle disease is present in many countries and chickens
need to be vaccinated more than once.

B. Chronic Respiratory Disease (CRD)
C. Coccidiosis
D. Mereks Disease
E. Avian Malaria
F. Fowl Pox
G. Infectious Coryza (colds or “sipon”)
H. Gumboro Disease (IBD)
48.
Avian Pest (NewCastle Disease)
Cause Virus
Transmision - Direct contact with the nasal and mouth discharges of infected birds
- Airborne transmission
- Through mechanical means such as being carried by sparrows (maya), predators, or
other birds.
- Human beings transmit the disease through infected clothes and shoes.
Signs - In young birds, gasping,coughing,ratting of the windpipe,hoarse
chirping,paralysis,abrupt drop in egg production soft shelled eggs, greenish watery
diarrhea.
Prevention Vaccination Consult your veterinarian for a program suited to your operation.
Treatment There is no treatment for the disease. In case of an outbreak, the following measures
could be adopted to minimize its further spread and effect control of the disease.
- Isolate sick birds quickly.
- Quarantine the area by regulating persons entering the disease-affected premises or
from other farms as well as from one poultry house to another.
- Revaccination of the birds if titer (detected by serogical test) is already low.
- Thoroughly disinfect the houses and premises. Allow to dry before occupancy.
- Bury dead birds deeply or burn.
49.
Chronic Respiratory Disease(CRD)
Cause Mycoplasma organism or pleuropneumonia like organism
(PPLO)
Transmission 1. CRD organism egg-borne; contracted exposure with
infected flock
2. Airborne transmission
Signs - Tracheal rales, sneezing, coughing watery or sticky
discharged from the nostrils.
- Foamy exudates in the eyes
- Feed consumption is reduced and the birds lose weight.
Treatment Broad spectrum antibiotics, either by injection or mixed
with the feeds or drinking water.
50.
Coccidiosis
Cause Microscopic organismscalled Coccidia (Eimeria Species)
usually occurs. In flocks below two months of age.
Transmission 1. When birds pick up or swallow the coccidial organisms.
2. Contaminated feed and water.
3. Indirect contact thru flies, human beings and other
mechanical means.
Signs - Tendency to huddle together in a corner.
- Decreases feed and water intake and poor weight gain.
Prevention Incorporation of coccidiostat in the feeds or drinking water.
Use of sulfa drugs. Most feed companies incorporate this in
the feed mixture as indicated in the feed tags.
51.
Mereks Disease
Cause Virus
TransmissionExposure to infected birds or to environment with existing
virus, poultry nests and feeders.
Signs - Initial symptoms are leg weakness and paralysis of one or
both legs.
- Birds tend to rest on their breast with one leg extended
forward and the other backwards.
- They could hardly reach the feeders and waterers
resulting in dehydration and emancipation which finally
causes death.
Prevention - Vaccination with MD vaccine, the most commonly used is
the so called Herpes Virus of turkey (HVT).
Treatment - There is no known treatment for the disease.
52.
Avian Malaria
Cause Microscopicprotozoan parasite.
Transmission Bites of mosquitoes, mechanically by blood transfer in mass
vaccination, caponization and injection.
- Severe anemia (paleness),extreme leg weakness,
emancipation and nervous signs like twisting of the head.
- The shanks and toes are dry and birds have ruffled feathers.
- Greenish-yellow or greenish-white diarrhea.
Prevention Control of mosquitoes within the premises and houses with
effective insecticides; include spraying the breeding places of
mosquitoes. Proper drainage of stagnant water.
Treatment Anti-malarial drops like plasmochin , quinine hydrochloride and
pyrimethamine combination were found effective. Confer with
the veterenarians.
53.
Fowl Pox
Cause Virus
TransmissionSpread by mosquitoes which feed on pox-infected birds; direct contact,
mechanically transmitted by visitors, wild birds and predators.
Signs There are two forms
1. Dry form –characterized by the formulation of black wart-like
nodules on the skin of the face, in the region of the comb, wattles
and around the eyes, causing the latter to swell and close. There is
usually profuse eyes discharge.
2. Wet form – characterized by the presence of whitish yellow growth
of the pharynx, larynx and windpipe. Because of the growth, there
is difficult in breathing which will result in death due to suffocation.
Prevention Vaccination with fowl pox vaccines. Control the mosquitoes by
spraying with insecticides.
Treatment There is no effective treatment against the disease. In the wet form,
removal of the wart-like growth in the throat usually loads to recovery.
In the dry form, the early application of Tincture of iodine directly on
the wart-like growth has been found to give beneficial results.
54.
Infectious Coryza (coldsor “sipon”)
Cause Virus
Transmission Through the air, direct contact or through contamination
of the feed, water equipments.
Signs - Swelling of the face and wattles and discharges from
the nostrils, which at first is watery, but comes sticky
and with foul odor as the disease progresses.
- In laying flock, egg production decreases.
Prevention Strict sanitation of the farm. Isolate sick birds immediately.
Treatment Broad spectrum antibiotics applied in the feed and water
sulfa preparations are commended.

1. Start with clean birds.
2. Use footbaths with disinfectant before entering chickens house.
3. Use “all-in” and “all-out” Management.
4. Do not mix ages or species.
5. Reduce contact with wild waterfowl.
6. Clean and Disinfect.
7. Limit access to poultry Houses
8. Vaccination.
57.
Protecting people
Not onlythe welfare of your chickens but also the welfare of people
who care for poultry should be protected. The workers should always
wear protective outfits like boots and mask (if necessary).
It is very important to know that a person should not permitted
to go nearer the chicken when they are sneezing or coughing.
Washing hands before and after feeding the chicken is important.
58.
Meat production
If you'reinterested in raising chickens for meat you'll need to do things a little
bit differently. There are some additional steps to consider as well -- for one,
slaughtering, processing or butchering the birds when they are fully grown to
market size. Chickens raised for meat are commonly called "meat birds" and
are usually a different breed from layer.
You'll have a lot (usually 50 or more, although you could just raise a few) of
fast-growing birds, which means a lot of poop. And the biggest question to
answer: can you handle saying goodbye in six to eight short weeks? Whether
you slaughter them on-farm or take them to be processed, if you're a new
farmer, you will need to face this reality, or be a vegetarian farmer. It's up to
you - but it's cruel to meat birds to let them live longer than a few months as
they are heavy-breasted and can die of heart failure if they grow too big.
59.
Marketing of broilers
ForContract Growers
Birds that have attained the marketable weight should be sold. Birds should be
harvested as scheduled. When harvest schedule approaches, the company’s
representative should be reminded of the exact date that birds are to be
harvested and the assurance that his company trucks should come on time.
This is to ensure that the birds will not consume extra feeds due to longer stay in
the farm without any beneficial effect to the grower.
The birds should be harvested within the shortest possible time. There are
companies that sell to viajeros. The middlemen tend to select the bigger and
healthier birds of relatively uniform sizes. This practice should not be allowed
since this will disturb the other birds resulting to weight losses and also delays
the harvesting.
60.
For Independent Growers
Alternativemarket outlets should be surveyed even before deciding to broilers to be
assured of a ready market at the time of harvest. Marketing arrangements with local
hotels, restaurants, cafeterias, institutional buyers and grocery stores with freezers
should be made.
Producers should form associations or market cooperatives so that they could agree on
a common price. Organized producers have some bargaining power with regard to their
selling prices.
Producers will be best advised to compute which is more profitable to sell, the birds
dress or live, and whether to sell at the farm or bring them to market.
The broilers should be sold at optimum, weight. More profits can be derived if broilers
are sold between 1.3 to 1.5 kg. Live weight depending on consumer’s preferences and
market reports.
61.
Egg or layerproduction
Management of the layer flock
Pullets are transferred to the laying house at the age of 16-18 weeks or at least 3 weeks before the onset
of egg production.
A few days before and after the transfer, the bird’s ration should be fortified with multi- vitamins to
minimize or counteract the effects of stress.
Cull those birds that show little or no promise of becoming potential layers.
Birds will start laying when they are 20-22 weeks old. Generally, pullets reach maximum egg production
when they are between 30-36 weeks old, after which egg production tends to decline and then levels off.
After the first year of laying, the layers undergo a physiological process called molting. Early molters are
poor layers while late molters are good ones.
During the second year of production, the layers usually average about 10 to 20 percent fewer eggs as
compared to the first year but the eggs are bigger.
Provide layers with calcium supplements like LIMESTONE and GROUND OYSTER SHELL and INSOLUBLE
GRIT.
62.
Tips on layermanagement on hot climate
Ventilation
1. Air movement around birds at floor level has a beneficial cooling effect. In
shade houses, take full advantage of natural breezes using paddles or
circulating fans in periods of still weather and particularly during the heat of
the day. In controlled environment houses, use inlets with movable louvers
which can direct moving air directly on to the birds at floor level.
2. In controlled environment houses, over-ventilate during the cool part of the
day in order to cool down the whole house. Birds experiencing a cool period
each day are better able to withstand hotter-periods with no adverse effects
on performance.
63.
Floor Space
1. Providebirds with up to 100 % (depending on severity of
conditions) more floor space than is recommended for
temperate climates. Three birds / square meter is an
absolute maximum. In controlled environment houses
rearing males with females makes the most economic use
of expensive floor space.
64.
Litter Management
1. Maintainonly a very shallow layer of litter on concrete floors. This will
maximize any cooling effect which the concrete floor may have on the birds
through absorption of body heat.
2. Dry dusty litter can cause serve irritation and damage to the eyes of chickens.
Avoid dustiness by sprinkling water generously on litter at regular intervals.
This spraying can, during extremely hot, dry spells, be advantageously
extended to the birds themselves and the feed.
65.
Water supplies
1. Wheneverpossible, use a water supply such as well which provides cool water.
Water consumption can double in very hot weather.
2. Bury or insulate water pipes to maintain the original coolness.
3. Supply troughs in which breeders may dip their combs and wattles so that
evaporation of water cools the blood supply in the combs and wattles.
4. In extremely hot weather, when water consumption may be doubled to prevent
heat prostration, do not place drugs or other substances in the water which
might decrease its palatability and, therefore, its uptake. The distribution of
waterers should be such as to minimize the distance any bird has to move in
order to drink; ideally, both feed and water should be distributed so that no
bird has to move more than 1 ½ meters to get its requirements.
66.
Lighting
1. In shadehouses, natural daylight must be supplemented with artificial lighting in order to
obtain desirable lighting patterns which are necessary to adequately control sexual
maturity. A constant or decreasing lighting pattern during rearing is essential to prevent too
early sexual maturity. An increasing or constant light pattern is necessary after 22-24 weeks
of age.
Egg Handling
1. Supply at least 1 nest per 4 females. Ensure free circulation of air round the nest areas to
discourage broodiness.
2. Collect eggs more regularly than in temperate areas and transfer immediately to the egg
cooling room which should be located on the farm site. Transport eggs to the hatchery in
an insulated van.
3. Practice daily fumigation of eggs.
67.
Nutrition
1. In hotclimates, poor production, small egg size, and thin shells are generally the result of
an inadequate daily intake of the required nutrients.
2. Where feed consumption is lowered merely by depression of the appetite and because of
high temperatures during the period of bird activity, there will be an inadequate intake of
ALL nutrients. This can be corrected by allowing the feeding activity to occur during the cool
part of the day, when appetite is stimulated. Additionally, if facilities allow, advantage can
be gained by feeding damped or wet mash, as can the substitution of mash by crumbs or
pellets
3. Generally, in hot climates, the energy requirements of the hen are much reduced; because
she eats to meet only her energy requirements, this result in an adequate daily intake of
protein, vitamins and minerals. In this situation, the correct daily intake of nutrients can
only be achieved by correct feed formulation based upon a denser ration in which
particular attention should be given to increasing vitamin levels well above temperate

4. The correctformulation of feed depends upon local conditions. It requires a
knowledge of the relationship between energy content of the feed and the
amount of feed consumed daily. With correct formulation the latter will contain
the correct daily allowance of protein, vitamins and minerals. Some vitamin
supplementation can be done via the water and a continuous level of vitamin
supplementation is virtually essential during all periods of heat stress.
5. Feed intake is the main method of controlling sexual maturity in open houses
and very careful attention must be given to controlling quantities very often to
levels much below those used in temperate areas.
6. Where intake levels are severely controlled, check weighing of the birds is
absolutely vital. It is also essential to ensure ration formulation particularly in
respect of any drug inclusions such as coccidiostats.

Marketing of eggs
Survey market outlets before investing in egg production. Marketing
arrangements must be made with local bakeries, local hotels, restaurants,
cafeterias, groceries, or sari-sari stores, higher income families and other
regular users. This will ensure regular orders for the eggs.
Sell graded or classified eggs. Proper grading or classification can attract all
types of consumers. This would also enable the consumers to make
purchasing decisions on the egg size at hand.
Sell only clean eggs since everybody wants clean eggs. Dry or wet cleaning of
eggs should be a standard practice on the farm.
Reduce breakage and spoilage of eggs to the minimum. Broken eggs
constitute losses and render the container unsightly.
