3. 1. Beak- The beak is a multi-functional tool used for pecking,
grooming feathers, eating, and drinking. It has no teeth, so
chickens swallow their food whole or use grit to help grind up
food in their gizzard.
5. 2. *Comb and WattleS-These are fleshy, red structures on the
chicken's head. The comb helps regulate body temperature, and
the wattles may play a role in attracting mates and expressing
emotions.
6.
7. 3. *Eyes- Chickens have well-developed eyesight, allowing them to
detect motion, see in color, and perceive a wide range of visual
stimuli. They have a third eyelid called the nictitating membrane
for protection.

9. 4. Earlobes- Chicken earlobes come in various colors and are not
just decorative; they can indicate the chicken's breed and
sometimes egg color. They also play a role in hearing.
10.
11. 5. Feathers- Feathers provide insulation, protection, and aid in
flight for some breeds. They also play a role in courtship and
communication through displays like fluffing or raising feathers.
12.
13. 6. Wings- Wings are primarily used for balance, communication,
and limited flight in some breeds. They also help chickens express
emotions and regulate body temperature.
14.
15. 7. Legs and Feet-Chickens have strong, scaled legs and feet
adapted for scratching, perching, and walking. The feet have claws
for gripping surfaces and scratching the ground to find food.
16.
17. 8. Digestive System- Chickens have a simple digestive system
consisting of a crop (for food storage), proventriculus (glandular
stomach), gizzard (muscular organ for grinding food), small
intestine (for nutrient absorption), ceca (site of fermentation), and
cloaca (common opening for excretion and reproduction).
18.
19. 9.Respiratory System- Chickens breathe using lungs and air sacs.
Air sacs help maintain airflow during both inhalation and
exhalation, enhancing respiratory efficiency
21. 10. Reproductive Organs- Hens have ovaries where eggs develop,
and roosters have testes that produce sperm. Fertilization occurs
internally, and eggs pass through the oviduct before being laid.
23. Each body part of a chicken serves a specific
function that contributes to their overall
health, behavior, and survival in their natural
environment or human care.
