We've had our bird for a couple of years now. Bought him as a hand-raised chick. To me he is very affectionate and will spend all day on me if he was allowed. He has always "hated" my husband, attacks him and latches firmly on his ears or fingers. He now "hates" my son (16) and will show signs of aggression to him. He loved my older son, but he is overseas now. So the only time I can let him out of his cage is when I'm home alone. His screeching has gotten worse now as this doesn't happen very often anymore. I've been covering him up when he squawks or moving him to another room or outside. My husband and son want him gone...but he is my best friend when I'm home alone.....what to do
