I need some advice. I haven't had to deal with something like this yet and am a little lost. I have year old buff orps and white leghorns. In April I picked up two black australorps. I figured they were just kind of shy because of the age difference until today. I moved them into the main coop about three weeks ago. I have two roost levels. Everyone goes to the top except the black australorps. I didn't really think much of it because all my chickens started out there when they first started out then eventually moved up. This morning my white leghorns full out attacked them. I had to run and pull them off. I let them free range so I'm not worried about the yard just yet. My concern is I want all my chickens to have a happy life and obviously the black australorps are being denied that right now. What can I do to correct this issue? Should I put them up top one night so they all wake up on equal ground? I thought about rehoming the white leghorns, but I'm already their second home and the guilt is eating me. Any help would be greatly appreciated.
