Really??? A BIRD???

I think I've lost my mind. We've "adopted" a rescue bird. It's a Sulfer Crested Cockatoo. So, let me just add, I am not a fan of birds, however, my pet loving family is. So as I sit here, he keeps saying "Whatcha doing?" over and over and over and over, lol - or at least that is what it sounds like. The family who gave him to us - NOT the person who abused him, said he likes Flaming Hot Cheeto's, Chicken McNuggets, and McDonald's Fries - REALLY??? Birds eat those things? And so, there is a knock at the front door - knock knock - the dog begins to bark, and so does the BIRD??? Really??? A barking bird??
