My wife has an African Grey, he is having trouble grasping perch, has had his nails trimmed, they had been left grow by previous owner. We have had him about 1 year. A few months back he got out unattended and landed on the cockatoo's cage who nipped off the end of one toe. Back to the vets for that, seemed to heal but had difficulty getting balance on perch. We were gone for week end and had him cared for when came back he was out of sorts, feathers huffed etc. Not able to perch, wife confined him for a bit as he kept falling off perch, and she was afraid he would be hurt. He is sore and tender and not using the one foot well. Now she is hand feeding him, what can we do? No avain vets in this area, All advice welcome
