So I recently just rescued an African Grey from a lady who should of never took the responsibility of having this bird. She said hes about ten but he seems alot younger than that. I got him becuase she said he plucked his feathers. So we brought him home changed his diet which he loves & he seems pretty content. He climbs out of his cage & makes a few noises like he "woofs" and makes the water dripping noise. But sometimes he fluffs his feathers up and he will nibble at my fungers and put his head down when I try to get him out of the cage. Sometimes just out of nowwhere he will just lash out and bite me hand or do something wierd. He doesnt like his wings touched. I just want to gain his trust even more than I have and he seems pretty attached to me Im the only person that can get him to step up and he whistles for my attention. So any suggestions?
