My female budgie Pickett is acting a bit aggressive toward my male budgie Phoenix all of a sudden. They usually preen each other and cuddle up and hate to leave each other’s side, but recently she has been screeching at him when he gets too close and bites at him when they’re eating. He hasn’t been hurt but her behavior is worrying me a little. I’ve heard female budgies can be bossy but she’s never acted like this before?
