I have an old buff orp rooster that some runaway renters left at a house up the street. He is starting to get his feathers back and he has a sooty colored tail coming in . I am assuming this is a big flaw for the breed? I have a very nice orp hen I got to go with him but I may need to get rid of him since he was abused by thier kids and now wants to flog preteens. Also he has a red tint on his legs. Is this just a flaw or indication of something else?
