I recently 6 months ago moved my cockatoo to a different room. He seemed to be ok with this in the last few weeks if I don’t take him out of his cage he bites me hard which he never did before and then he loves me like I am his mate. Now I don’t trust him. Please help. I’m at my wits end. I love my bird and love to cuddle with him but now I’m worried. He has bitten me on my lip for no reason and now recently he went after my hand. I used to be able to put my hand in his cage. Now I can’t get anywhere near his cage. One night he dive bombed me through the cage. I was so upset I cried the whole night. Please help me. I have had her m fir 23 years. Heartbroken
