i have 2 budgies one i definitely know is a boy but we think that the other one is a girl but her cere is changing colour all the time and i dont know why? but i read that female budgies have stronger jaw muscles than males and she has a really hard bit compared to the male so i am really confused........

Maybe a picture would help with sex of bird in question?

Female ceres do change color.
