I am building a coop for my silkies that are about 2 months old and way to big for there brooder . I have 7 other chicks that are about 2 weeks old. I have 3 Americauna chicks and 2 of them are huge. They were in the other brooder, but they were trampling the other chicks so I moved them in with the silkies. I was wondering If I could put them out in the coop with my silkies. I live in a small neighbourhood and the only predator is my kitty. If not, when can I put them in?
