My amazon parrot PD (13 years old) HATES change. Earlier today, for example, I brought in a new printer to install. Just seeing the new object in the house threw him into a blind rage and he was determined to attack me and the printer until nothing was left. He's the same with anything. If I change my clothes at a different time than usual, if I open a drawer he's never seen me open before, anything outside of his usual routine will send him into such a rage he won't stop until I've banished him to his cage for time out or he's decapitated me. Thankfully that hasn't happened yet. I'm not sure how to fix this issue. It's getting to the point where he's more angry than friendly with me, and it's really killing our relationship. I'm tempted to rehome him if I can't figure out a way to change things around in the house without risking life and limb. Any ideas on how to keep him calm?
