Ideally you should add a laying box with some substrate like sterilised peat/ vermiculite or sand. Temps for it should be approx 28c for laying conditions. A small tray like a kitten litter tray or similar would be ideal!
If they arent already i would seperate your beardies from now on. Speak to your rep vet and let them know the situation. You will need to keep an eye on her, if she is going to lay there is a chance she could become egg bound which requires immediate veterinary treatment.
Has she gone off her food? Thats a good sign along with the digging. Have you had experience of breeding before?
