I decided to keep my eight chickens in one of our horse stalls. My husband installed hardware cloth over all of the openings between the boards and bars, and used a tight netting over the top, so that predators can not get in. The stall opens to the outside paddock with a dutch door - so they get out every day. I have prefab nesting boxes mounted on one wall and have used two jump standards and a rail for a roost. I guess I got carried away with repurposing and not buying extra stuff. The chickens are very happy in their 12 x 10 stall, and I get to go in and sit with them comfortably whenever I want. This is working very well for us right now, and is as easy to clean as any other horse stall in the barn. Also, all animal feed is kept in the same area and it will allow them a bit more room to roam in the cold Minnesota winter, when the snow is several feet high and getting outside is impossible.
