We just inherited 4 silkies and 2 Ameraucanas from a friend. We have seperate coops for both because they fight. We live on an acre and have neighbors right next door on both sides, so the possibility of allowing the chicks in our yard is pretty slim .....unless you have suggestions,lol! The main issue is, if we can't allow the chickens out in the yard, how large do the chicken runs need to be? We need 2 seperate runs, large enough for 4-6 birds each, as we may be getting a few more hens. Also, how big for the nesting boxes, and any other pertinant info. thanks!
