Yesterday, I received a rescued B&G Macaw. It is an assumed female, who was abandoned. Tenants moved out of a rental house and left her behind - locked in her cage for several weeks alone. I've owned parrots before, but not one in this horrible shape! I'll start looking for a good avian vet tomorrow. But I'm trying to make her as comfortable as possible until I find one. She's getting rehydrated, eating well, and already dancing for me. But she hasn't got a single feather or piece of down on her entire body. She only has her longer wing feathers, her tail feathers, and then feathers on her head where she can't reach to pluck. On payday, I'm buying her a "hoodie" from flightquarters.com to help her stay warm. But I'm wondering if the plucking was JUST stress from being left alone and abandoned, or if she may have an underlying illness I can treat. She does seem to have one raw area, right on the middle of her breast, just beside the sternum. It's about an inch long, and maybe half an inch wide. More importantly, last night she kept shaking her head and twitching - a sign of mites in most chickens. I doubt she slept all night. But despite having almost no feathers, I see no sign of mites. So what else would cause her to twitch so much? And what is the best treatment suggested until I can find a GOOD avian vet?
