Hi everybody! It's been a while since I have been on this forum, but I came across a problem with my Ancona duck. She seems healthy, eats a lot, and I mean A LOT (anything she can get her beak on), but she has these bad scabs on her back. The scabs are hidden under her wings and a bit of plummage but it seems like its covering the new feathers trying to come up. The scabs are big but I don't believe she has had any major fights with anyone. I have two other ducks but neither of them have scabs... Could she have mites or lice or ticks? I'm posting a few picture, but it was hard to get good quality ones that conveyed the size of them.
