I've tried the tight fist thing.. He still manages to bite and puncture my skin..... He did it only the other day, I was playing with him on the top of his cage.... Kissing him etc. I put my hand flat on the cage top and he reluctantly puts one foot on and steps off..... This is obviously a trust issue at the min so I thought I'd keep doing it until he gets both feet on.....after a few attempts both feet are on my hand so I praise him and leave my hand still so he can step off at any time... Which he did... I thought, yes! What a break through... The day after he did exactly the same but only this time when he put both feet on he proper head butted my hand he was stood on biting hard at either side of my middle finger puncturing the skin... I don't usually pull away if I can help it but this time my reflexes got the better of me and before I knew it sam was hanging off my finger with just his beak...which inevitably he crushed into my finger harder in order to hold on tight!!!! Not impressed at all!
