I got up this morning to find a couple babies with raw spots on their wings. I was wondering if it was because they are loosing their fluff and getting feathers or if my duck is picking on them? I separated them from the duck and I know they are not doing anything to each other, but the duck has been protective of them, especially the smallest one, until now. I am not sure if it is trying to groom it or if it is picking the fluff out. Is there something I can do to help it? Something I can put on its wing or should I leave it alone?
