My daughter’s Starlight Green Egger has a black spot on her wattle. I was unable to remove it. It felt adhered to the wattle—like if I kept trying to get it off I was going to pull off part of the wattle...almost scab-like. She is the only hen with this, but I did find a couple of what I think are red mites on the comb of another hen, & I will be treating the coop & the whole flock for mites. This black scab doesn’t look like a mite, though. I’ve been searching online & can’t seem to figure out what it may be or what should be done about it.
