Perhaps not breeds so much- but standard vs bantam. I currently have some Welsummers, Ameraucanas, and Silkies living in the same coop. I shut them in at night, and during the day they free range around the property (about two acres). I am going to be adding some more birds to my flock- including some little golden sebrights. Should I build a different coop to keep the bantams in? One of my Welsummers is a rooster and I'm worried that he's going to injure my silkies (and would definitely injure the Sebrights!) one of these days when he tries to mate with her. Is it entirely useless to build a separate coop for the bantams if they're all going to free range together during the day? Any advice would be appreciated, thank you!
