My chicken's coop is a stall in the back of our barn, about 10x10. They have an outside fenced area about the same size. I still need to make them nest boxes and a door on the stall to keep the cold out. Nothing fancy, but they seam to enjoy the space. They also get to roam the yard when someone is home. The perches are made from branches and wood scraps. There are a few pics of them in the yard. One was when they where younger. One pic is looking out the bard doorway. The blue thing is my parrot in her traveling cage.
