Hi PDM,....
Best of luck to your friend and her little bird. We are all pulling for them!
Thank you, kksuns, and for all the suggestions.
I have sent all of the ideas to my friend and she is extremely grateful for the help.
She has already spoken to the vet about previous suggestions and he is looking into them.
I don't know what the actual diagnosis was, but maybe I'll find out when I hear again.
Thank you again!
Thanks to all who have helped and offered good wishes

I'll keep you updated if I can.
