So I have a bantam Roo and a bantam hen. They are in with my standard birds and get along with them fine. I've noticed lately the hen submits to my large black Austrolorp Roo though and he is so big his feet literally slide off her back. No injuries so far but I'm a little worried for her as he fills out. He is very big but still lean being a super slow grower and only around 6 months old. Should I build them a coop or do you all think it will work out okay?
