a year and a half ago, our family got a young African grey from a local breeder. when we first got her, she was unable to step up, but after a while she became hand tame and developed a trust with me. i played with her every day and i would be able to flip her over to tickle her belly. but after that, i had to leave to study abroad. I thought that my family would be able to take care of her but she always had a closer bond with me. Now its been 9 months and i have returned just to find that she has forgotten me... She would bite when a put my hand in her cage and when she climbs out she refuses to step up. What should i do? its as if she thinks I'm a predator! i feel really bad and do wish to regain her trust.. any help would be appreciated.
