Worldwidestations. Infrastructure must be developed and implemented to Design is exceedingly important to the development of sustainable infrastructure. The first rule of sustainable farming is you populations continue to increase currently we are able to feedexecute this much-needed research. The integrated pasture must sustain the farmer this primarily means all infrastructure must be designed in a manner to allow the farmer to perform everyone on the planet however, in the future the green revolutionpoultry infrastructure project created the infrastructure needed to maintenance and managerial tasks as easily as possible. will not be enough.

The brooder house can house productive agricultural land to feed the world’s growingallow for the long-term study of soil quality and fertility, as well 100 chicks for approximately 2 weeks. This house also doubles a breeding house that can hold 15 adult chickens. This house population. As the US civilization moves into the future we mustas the ability to determine whether or not this integrated system was constructed on an old 6’ x 8’ trailer. find ways to do more with less agriculturally. The other majorcan cut down on the carbon inputs needed in traditional orchard problem facing conventional agriculture today is peak oil, as oilmanagement. The finishing house was designed without a floor so that all the manure will be directly deposited on the ground. This reduces prices increase so does the cost of most conventional agricultural the amount of litter needed as well as reducing the amount of time it takes to clean out the house. Once the chickens have production methods. Systems as well as agricultural methods must fouled the inside of the house the house can simply be moved to a new clean location. The light weight design enables one evolve so that current agricultural production levels can be person to do this, the finishing households approximately, 50 chickens for six weeks and measures 4 x 10’ at the base. maintained using fewer fossil fuel inputs. This project is an attempt to create the infrastructure needed to study an alternative The laying hen house must be portable to avoid erosion issues and have easy access clean out doors to encourage good agricultural management practice that could prove to be highly management and sanitary living conditions for the chickens. Another requirement for the henhouse is that it is on wheels so, it sustainable increasing soil quality and fertility as well as can be easily moved by three people. Laying boxes are located on the outside of the house for easy egg collection. This laying decreasing carbon inputs needed in fruit orchard production. henhouse was designed to house 75 laying hens and measures 6’ x 24’ it comes apart into two 6 x 12’ sections to make moving Without this meaningful research we will not be able to develop it through the orchard trees easier. agriculture in a manner to sustain future population increases. movable brooder house on pasture Freedom Ranger check 3 day old Materials There are three types of chicken houses needed to conductthis study a brooder house, for starting all baby chickens orchicks.
