What sort of disease could cause skin leisions like this? She is being treated for an inner ear infection, but the leisions are eluding me when I try to look up what it might be. She has been treated for lice and no critters can be found now. She constantly picks at herself and pulls out her feathers. Her leisions are very sore to her. I have been trying to rub some bag balm on them, but it seems painful to her. Any thoughts are much appreciated. Thanks so much.
