I have a small flock of Buff Orpingtons. There were 2 roosters and 8 hens. Someone bought one of my roosters, and apparently he was the dominant one. Now my remaining roo is just one of the gals. He is a year old. He has never crowed. I've put him in isolation for 2 weeks and I put him back in with the gals and no change. Please help. Am I going to have to trade him off?
