My buff minorca has some type of growth on her earlobe. It almost looks like a small clump of dirt. I pulled (gently) at it and can tell that it will tear the earlobe's surface and probably bleed if removed. I cannot seem to find anyone else with a similar issue. On the same hen, I've noticed small black spots on her comb. I have no idea if the two are related or if either issue is a cause for concern. No other symptoms; she is acting and laying just fine. Thank you!
