Our cockattoo is chasing our 12 year old daughter
We recently purchased at 27 year old cockatoo. At first she was only sweet but two weeks after we got her she started chasing my daughter around the house biting at my daughters feet. My daughter loves her and spends time with her but out bird just started this behavior. She also lunges at my head when she is out of her cage. Can anyone please tell me why she does these things and how I can get her to stop?
