I purchased a 13 year old yellow crown a week ago. My first advice to my family was for everyone to talk to him. I had previously had a Quaker who absolutely HATED my adult sons, and would go into attack mode every time they visited, so I didn't want a repeat of that! As luck would have it, it is ME the zon doesn't like. Other family members can pet him, and he has even stepped up on the shoulder of my son. When I approach, however, he turns the other way and walks off! Last night he even bit me when I tried to put his feed in. Will this always be the case, or what can I do to acclimate this bird so he will like me?
