I was told the plucking started after the death of the owner. Apparently a lot of people in and out of the house crying and everything sent the bird overboard. He is step trained and I've laddered him a few times successfully. Nobody let him out or touched him after his owner passed due to fear. His old cage was in a sad state. I have his door open all the time, but like some career felon, he hangs out by his food bowl and watches me. No interaction with his toys. And he has plenty of em.
He is eating vita pro mixed AG seed with some hemp seed mixed at 20%. He has a vitamin block, and has bottled water. His wings aren't clipped but he can only fly a few feet. He seems to be improving. He started preening and grinding last night.
He is not interested in stepping up when I put my hand in his cage. When out after a hour or so he will drop his head to prevent me from putting my hand in the step up position, hoping to stay out all night. When I distract with the other hand he flies from cage and steps up immediately when on floor.
Thanks everyone. I have Eclectus experience, but this grey has had it rough and I never rescued one before. Oh, by the way, Vet says he is in good shape medically, but shows some atrophy.
