Hello, we just brought our blue and gold Maui home 2days ago. He is just over 4 months. He is super sweet, and loves to play and be handled, however he is not yet aware of the strength of his beak. He has gotten a hold of our fingers a couple of times, and won't let go... we need very basic bite pressure training steps. Also, any time we hold him on our arms he climbs right up on our shoulders and heads, what are some good ways to teach him to stay down? Thank you so much for your help!
