My Grey is almost four months old and has been with me about 3 weeks. She steps-up pretty good on command but immediately moves to my wrist instead of staying on my fingers. I keep my thumb folded and the fingers straight and aligned like a knife. I don't want him to get the habit of sitting on my shoulder but he was allowed to do it by the breeder. How can I get her to stay on my hand. I have thought about using a cardboard cone like used on cats and dogs, on my wrist.
