I'm moving my birds from one place to another and I have built two hoop coops. In their old coop they had a nice big coop to go into every night and it had the sleeping roost and the nest boxes inside. In the hoop coop I plan to use milk crates for nest boxes, but I'm kind of drawing a blank as far as a nice cozy place for them to go in to sleep at night. If I put a roost up, and just kind of enclose it on 3 sides with the front open is that enough shelter? It gets to about 25 degrees on a cold night. We have a rare colder night than that here in the foothills of Mt.Rainier but its not like we are in the cold Midwest or anything. What are your ideas?? Pictures?? I'm using all reclaimed wood because that is what my budget allows.
