When we first brought our bird home, he was of course scared. She eventually settled down and allowed us to get close, I was even able to rub her neck, or her belly. After a few month, she is the exact opposite now. She bites extremely hard to the point where I take my hand immediately out of the cage in pain. Imagine getting jabbed with the biggest needle! The only time my bird is good with me is if I have a treat for her, then she will sit on my finger, or right in my hand. Other than that, her behaviour has changed.
Is it because she is frustrated? We haven’t let her out of the cage yet. On a side note, we haven’t done anything to scare the bird. We do have multiple people walking in the room (living room)
The female loves to bite and chew, and that is normal. Provide her with a lot of toys, foraging toys.
