I have a 4 year old rooster that has no tail feathers. He is a very nice rooster. Had to rehome another of the original roosters. I think some of the hens are pecking at him. I have tried to keep him sprayed with the blue stuff but the feathers are not coming back. No mites, etc. Should I separate him to let his feathers grow back out? He is the original rooster for my flock of 42. We have another rooster that is about 2 years old now and they do get along. Open to suggestions. Thanks
