It's like a human female that's pregnant, when they go to the bathroom for #2, sometimes they end up going into labor because it's near their term and they push too much.
In another thread (June 21) you said she laid 38 eggs...she should have laid them all at that time. Its not usually good news that she continues to drop eggs.
Putting the container back in may help...but it might not too. If she continues to drop eggs I would take her to the vets.
