My bird has been in breeding condition for months. Here cere changes colors slightly but stays generally a shade of brown. She starts to come out of it and then goes back in again. I have changed around her cage, which helps for a few days sometimes. Before I thought it was because she was getting too much light but now it is not light for very long each day and the closest window to her faces north. On the plus side, she has never laid an egg. Should I be worried about this?
