I'd noticed 1 or 2 of these before, and didn't worry because they didn't seem to be anything to worry about. Now I'm noticing more. When I give them a gentle scrape with a fingernail, they seem to be part of his comb, not anything attached. He seems fine every other way, and he doesn't seem to be bothered by them at all. Are these just pigment spots, healing spots from bug bites or scratches, or some sign I should be worried about? He'a a 1 year 1 month old Ameraucana roo, and we LOVE him dearly. Any insights?
