This is a stationery design for a 12' by 8' chicken run, complete with roosting areas and hatchling boxes. The 96 square feet of space allows plenty of room for interior roaming in the aviary, while the raised nesting box provides an extra level of security from predators. It also helps you isolate your chickens when you need entry to clean, feed, or repair. The coop can house up to 15 adult birds, and with its gable design and proper insulation, it can provide plenty of shelter in even the harshest weather.
This design is for farmers entering the chicken raising business, but with a desire to expand. The dual hatching cases allow for ease of egg collection and hatchling recovery. The included stairway helps your chickens enter the raised nesting area. Multiple access doors make cleaning, feeding, and harvesting a snap. Use of a certified electric heater can also help during especially harsh winters.
