I have all of my birds in the barn but it still does get cold in there. We made a coop out of an old concrete silage that was torn most of the way down to about 5-6 foot tall. It has a metal pointed roof on it, the door (metal wire) is inside the barn where the cows are, and has a light from the ceiling. There were holes where the concrete and roof meets that we stuffed hay in. We have nests and roosts for them to get on. We put hay on the floor but they just trample it into the other old hay and poop. We have chickens, 2 muscovy ducks, and a giant white tom turkey in there. We are having a hard time keeping the floor dry and the water from freezing especially if the wind is blowing towards the silage. The turkey is to big to fly to roost, the ducks haven't been roosting even with the lowest roost only being 5 inches off the floor, and the younger chickens lay near the door during the day instead of roosting. So the birds are getting all covered in poop. It's already been around -8 at night but from what my father-in-law said that some winters can get almost -20 below. We have other turkeys in a warmer pen right now. We tried to have the chickens in it last year but they kept finding or making holes to get out. My big RIR/Leghorn roo has gotten the tips of his comb frozen. I'm not sure what to do with the chickens since the floor is so wet with poop. We have one spot we try to pile the hay in to make it thick for them to get on but it doesn't last long. There is also a long big cage we built for the young chicks when they out grown their box that we have stuffed hay and nests into it. I don't know how everyone keeps their birds clean during the winter and summer. Mine are outside in a huge fenced area and they still get dirty. The older ones even fly over the fence and go out into the camel field and under the apple trees. We've been laying cardboard boxes down also for them to roost and walk on.
Here's some pictures of them.
