You might know that I have a greenwing male about 3 or 4 years old. He is bonding more and more with me while my partner is not around but when she is, Jack, my greenwing turns into a demon and want to hurt me lol. I was wondering if anyone has had experience with a previously owned macaw like this before. I want to try and work on a spin off of a step up training where her and I work on "up up" between eachother?... if I put my hand behind him and ask he usually responds but tries to bite. I do the "little earthquake" to distract him from biting me. Will this help with his agression while she's paying attention to him and im a threat to that attention?
