so I have had 2 African greys for about 5 months now and I understand the one takes several months to warm up to anybody at all but we get along, the other however isn't shy at all. when I open up the cage she is the first one out but will deliberately climb down and across the house to do nothing other than try to bite me. ive tried ignoring her, iver tried a squirt with a water bottle when she bites, ive tried giving "the look" and firmly saying no biting while trying to keep my cool and not flail my hand around when she clamps down. but what is weird about it is my fiancé has no issues holding her or petting her. and our friends will come over and she wont even think about biting them and she steps up every time for people she has even only met once. I noticed it when I picked them up from the previous owners too and she bite me right away but showed no interest in biting my finance there or anybody else. any suggestions on my next step to bonding with this one since ive made great progress with my other grey.
