I acquired a cockatoo about two weeks ago. She is about 24 years old and she has bonded with my husband quickly. She wants to come and sit on me, snuggle in my lap, but within a few minutes (sometimes less than one) She bites me. They started out soft and got harder each timr. I am usually doing nothing when she chomps, except last two times I let her get on me I put my hand up to keep her from getting near my face (she drew blood biting my ear), and got two rather hard bites on my hand. I pushed her off me the second time she did this and have not allowed her to get on me since, though she tries to when we let her out of the cage while I am in the room. i am afraid of her, but don't want to give up on her and put her through another change of owners. Please help!!
