Greetings, everyone. I have made progress training my Meyer's to use his beak gently. However, one trigger that still causes him to lunge and bite hard is if I am offering him something he wants, other than food. For example, if I have an interesting toy or even a small piece of cardboard, and I extend my hand to offer it to him, he will lunge not at the toy but at my hand. I sort of don't get it - except maybe it is a kind of territoriality/possession impulse. Any experience with this? Thanks.
