I am a bit worried about the black scab that seemed to fall off my rooster's comb (just one side of his comb) today. I had noticed blood on his hackles this afternoon, just a little, not too much, but was wondering where it could have come from. Then I noticed his comb appeared a bit bloody. I touched the blackish scab on it, which I had not seen before. Later I noticed it had come off and his comb was raw and bloody where it had been. Not too bad, but noticeable. What do you think would cause a black scab like that, other than an injury? He does have some black scratch marks on his comb that I am sure are from snagging on something, maybe rosebushes. There seems to be an equivalent black scab on the other side of his comb that hasn't fallen off yet. He seems energetic and happy and has a good appetite. You don't think it could be fowl pox, do you? I'm in Salt Lake City, and I don't think there is much fowl pox here. He did sleep indoors last night, and I'm wondering whether he could have cut his comb on a drapery hook in the solarium, where he slept. Funny I didn't see any sign of it when I carried him outside at noon today. I hope he doesn't get frostbite in the bloody area tonight. It is supposed to get down to anywhere from 28 degrees F to 34 degrees F, depending on which forecast is right. I tend to think it will probably be down to 31 degrees F. This will be the coldest night he has slept outside so far, in the coop, with a white leghorn pullet on each side of him. I am hoping they will keep him nice and warm. He's happier with the hens in the coop than alone in the solarium, I feel.
