My albino female did this. Right after she shed it looked like she had absorbed the eggs. Foolishly, I stopped checking on her as frequently, and in about two weeks she had laid 3 eggs.
Since this is my first year, I can't speak about how common it might be, but don't do like I did and quit checking on her.
Thank you for the quick response. Was the clutch viable and did they all go to term with no issues?
