I'm getting some bantam silkies and cochins in April, and already have 2 silver sebrights. I'm wondering if a separate bantam coop is a good idea? I'm also getting some Polishes and I know they can get picked on. My coop is built inside the barn, kind of all around and wherever it will fit. There is an enclosed room (About 10'x12'?) within the coop that the chickens don't have access to because there is just junk and old hay in there. However, I was thinking of cleaning it out and making it into a bantam coop. It will take a good amount of work, but if it would benefit the bantams to have a safe haven I'm willing to do it.
