Thanks for the info! We got her a large plastic tub and put several inches of peat moss in it and set her in it, but she didn't seem to dig around in it. She just sat there until she could get out. I think we might not have had it warm and moist enough so we'll try again.
It's been about 3 days and still no eggs. She is eating a bit and moving some, but still does not want to climb up and down her cage like usual. How long does it usually take from the first signs to the actual egg laying?
