So I have begun clicker training my two birds. blu is tame and will step up on command. I am working on getting him to come to me. but Trixie is not quiet tame yet and I am trying to get her to step up on command. so I am training them together but separately at the same time. Trixie stays in her cage for now and blu can roam but I try to train him where his cage is because that is where he plays when he is out. when I go to train her he keeps butting in and stealing the millet reward from her... how do I stop that?
