We use our chickens to help with fly control around our livestock. They are free ranging currently in and around 2 20x40 tarp buildings that are open on ends. I have 2 small calf hutches that are dedicated for chickens with their nest boxes and roosts. The hutches are hard to get into and clean I was considering moving the roosts to above the hutches about 7 or 8 feet off the ground with a ladder up to it. Will this work and will it be warm enough for them in winter with one end of the building closed to keep out most of the wind?
