Leona,
You need to give her a laying container ASAP - or she will probably die egg bound.
What I use is a 32 gallon trash can. Put about 18 inches of 1/2 sand, 1/2 peat moss in the bottom. Mix well. Add really warm water until it is thoroughly moistened and will hold a tunnel. Take a small plant out of it's pot and plant it directly in the soil. If you have a small piece of light driftwood - place that on top. Add a branch for her to perch on. Clip a bulb on the side for heat.
Put it in a quiet place in the house and give her absolute privacy. If you bother her - she may abandon the digging process and become egg-bound. She may dig several test holes - and may dig for a long time until she digs a hole that is "right" for her. If she isn't finished by night time - turn off her light anyway. She will eventually turn around in the hole and have just her nose sticking out. When she's done laying she will fill in and cover the hole. Do NOT interrupt this process. Wait until she climbs back up on her branch. If she's not allowed to finish she will keep going through the motions indefinately.
When she all done - give her a lengthy warm shower - and bring on the bugs.
If at anytime she seems to be taking a downhill turn - get her to the vet ASAP. She may be oxytocin to complete the process or a section.
Best of Luck! If you have any questions or if I haven't been clear enough - let me know. I'll pop in here throughout the day - or call me at (780) 857-2003.
