I have a 25 year old Orange Winged Amazon that I recently rescued in May. He was badly neglected in his previous home and came to me completely bald. Since coming to me, he has regrown most of his plucked feathers but still has alot of "grey down". I recently noticed after leaving him with a friend for 2 weeks (to petsit while I was away) that his feet are "raw" or look as if they are raw. They had absolutely no interaction with him, as he is pretty aggressive towards other people and only fed and watered him. It is winter (just in-case the dry air has something to do with it) and those 2 weeks were the first time I've ever been away from him since he came to me. His perches are smooth wood (had to add that in-case that could be the problem). And he loves to walk around the house on the floor. There is nothing on the floor that would hurt his feet (ie. sharp objects, etc) and the floor is hardwood. He also climbs all around and ontop of his cage as-well as the bottom of it to "forage".
I've had Macaws for the last 10 years as-well as smaller birds and have never seen this before. He has seen several avian vets, but none can tell me what's wrong. Im just thinking the bottoms of his feet are raw (they're just a shade of pink), but if they are raw, is there anything that can be done to help them heal up or?
If anymore information is needed, please feel free to ask. And any help or suggestions would be greatly appreciated!
