Hello. I have had my African Grey for around 2 years now(that's her age) and her name is Goose. She has determined me her mate since day one. Always feeding me and doing tricks/ singing for me. All of a sudden out of nowhere with no changes in my appearance or her daily routine she will not step up and keeps biting to the point of drawing blood on me. I don't pull away and just deal with it, but I'm concerned for her health. Maybe she is sick? I keep reading about hormones as well. I just want my old GOOSE back! Please offer advice.
