How long has she been in there? If more than two days I would get her out and mist, water, feed and give calcium. Do you weight her often so you will know if she has lost weight? As I said it's very important that they drink and eat right after laying or she may have a problem.
Here's how the laying should go. Right from my blog.
While digging the hole they will be head first in the hole. Once they get the hole to their liking they will turn around and lay the eggs. Usually this doesn’t take nearly as long as digging the hole. Again, very important, DO NOT let your female see you looking. She needs complete privacy to lay these eggs. Once she’s finished laying the eggs she will start covering up the hole and then pat the sand down and return to the branch. Camille is always exhausted and once I see her covering the hole I get her out of the laying bin and return her to her tree. She is very weak and needs plenty of water and food. First I give her a really long misting to get all the sand off her and she takes several long drinks. Then I give her several feeders (silkworms are excellent at this time) heavily dusted in calcium with no D3. I would highly recommend buying some liquid calcium and keep it on hand for your female. Once I notice that Camille has eggs I give her a drop of liquid calcium once a week until she lays the eggs. After she lays the eggs I give her a drop or two every day for 3 to 4 days. If you don’t have liquid calcium, then heavily dust her feeders with plain calcium for 3 to 4 days after she’s laid eggs. I feed her very well the first fews days after laying and then after 3 or 4 days I put Camille back on her regular feeding and supplement schedule.
