My rooster has little bite mark and scratch like injuries on his comb and wattles and I'm not sure what to do about it. He has little sores/scabs, scratch scabs, and now he has little pustules on his wattles (one is open and looks like it was bleeding). I have no other roosters, are the hens doing this because they're bored? They like to peck food out of his mouth. What do I do to help them heal? He has some that have been there for at least a month now and are still not all the way healed.
