My bird ginger has been puffed up like this for a while but is acting normal. I had another bird named hope that passed a week ago because she was dying of heart failure. Since then, we got a new bird because ginger was getting lonely and I'm leaving my new bird cinnamon alone. We also changed to pellets and cinnamon seems fine. But ginger has been acting usual, she is very energetic and paces at the bottom of her cage when she wants treats. I'm just asking because im worried something is wrong. She's been like this for a week maybe.
