I keep trying to think of ways to help my birds stay warm this winter. I know, it's a ways off, but Colorado can have the craziest weather. Snowed on July 4th once... I'm not really worried about them in the coop (Eglu Cube) but I want to avoid cooping them up when the weather gets cold. Could a saddle work like a jacket? If I leave it on for a few days would it cause sores? Would putting a clear plastic tarp/cover over the run be good or would it cut down on ventalation too much?? I am receiving 3 EE chicks next week and they'll be about 4 months old when it starts getting cold out.
