We have an African Grey parrot. A congo I believe. When we first got him I was able to handle him and he was ok. Then he just decided it was my wife that he liked better. He continues to bite me and act aggresive when I attempt any contact. Is there anything that I can do in order to help he and I to get along? He is about two years old, and seeing as he is probably going to outlive the both of us, I would like us to all get along.
