So Mango is scared of hands and I want him to get used to my hands and not be scared using positive reinforcement.He will step up on my arm but not the hands.Mango's wings are clipped but he can still fly a good bit across the room and I regret clipping him.What methods could I use to make him not so scared of my hands? Obviously he wont take treats from me if he is scared of hands.I am also moving my Cockatiels out of my bedroom so they are not a distraction.
