One of my daughters Barred Rocks developed black spots on her comb about a week ago. They have gotten bigger and almost look scabby and now we are noticing them starting on her wattle. Two days ago we notice the same small black spots on her Red Sex Link's comb. I have tried looking them up and the closest thing I can come up with is possible fowl pox? I have attached photos of both of them. The close ups are of the Red Sex Link. Any ideas what this might be and how we can treat it?
