I have had my 30 year old cockatoo for a year and a half. Recently he started screaming whenever we have guests in the house and has to be shut in one of the bedrooms in order for us to visit. He screams the whole time they are here and as soon as they leave he stops.
He has known all these people since he arrived in our home and didn't do this until a couple months ago. I do not know his history as he was dropped off at an animal shelter in Colorado by an unknown person. I do not want to rehome him again!
He used to come out of his cage, sit on my shoulder, step up without hesitation and walk around the house, even when strangers were in the house. Now he has become aggesive towards me by lunging and trying to bite. will not step up, can't be trusted out of the cage when husband is home as he chases and bites him (which he never did before) and has become VERY cage aggressive when I am trying to clean it.
i have read all kinds of books and tried many different things and nothing is working. Please HELP!!! My husband is getting fed up!
