My little bantam rooster has this crusty, gray, puffy patches on his comb. He’s young, just about finished filling in his feathers. He’s housed with a little hen, but the two of them are isolated from the rest of my birds (because they’re so small). I haven’t found any sign of mites. I don’t think it looks like pox, though I’m open to being told I’m wrong. It isn’t frostbite (were in Florida). It is possible it’s from being nipped at. He was housed with two other bantam roosters previously, however, they’ve been gone for several weeks now. Any thoughts would be so appreciated!
