The green quaker parrot I have had for only a week has started biting at my hands everytime I get him out of the cage. I try my hardest not to react but when he breaks skin I wiggle my arm slightly so he loosens his grip. This is unrealistic to do everytime he starts biting and I feel it will harm my trust with him. He is only 5 months 2 weeks and 1 day old so I don't know if this is just a phase or what. I try to distract him by trick training but he tries to bite my finger after we stop. He picks off bits of skin and chews on them. What kind of behavior is this and is it likely just a phase to see who's boss?
