Still learning here, I noticed my Rooster (10 months old) has had some odd looking marks on his comb. He has been our only Rooster for a few months (we originally had 4). When I first noticed it, I thought he might have cut his comb outside or been in a fight but now I'm not sure. We have had some cold temps around here and their coop does have some areas where cold air could have come in. Is this frostbite or something else? Any and all help would be appreciated.
