About a week ago, I noticed these black spots on my black australorp's comb. I thought it was just scabs because she can get picked on a bit by the older chickens. Then, I noticed that they seemed to be getting bigger. I've heard about fowl pox, and I also heard that you can use a foot anti-fungal cream on the comb. But is this even fowl pox? And if not, can I just put noesporin on it?
