Hello,
Do you have your female housed with a male, or another female, or is she housed alone?
So, she is around 2 years old then?
The average clutch size is anywhere from 18-30 eggs. If there are no problems, she should lay all of the eggs all at once, though, it does occur where they don't lay them all at the same time which can be stressful on them.
Has she stopped eating yet?
Be sure to give her extra calcium & fluids right now.
