Hi,
I am new to the forum. We just got an older African Grey Timneh Parrot (Cookie). His/her has a bad eye, and can't fly according to the vet that we took it too. it is missing 2 toe nails, vet said probably got bit off, and on it's right leg its back finger is bent around backwards. Ours only uses 1 toe in the back cause the other is in the front stuck (tight). Walks fine though. not sure it it's arthritis?
