Hi Ryan,
I just read your thread below and I have a couple comments. As anson pointed out you need to keep the tub in there all the time and have a branch or vine so she can easily get in and out. Also make sure it will not collapse on her - I used a mix of moist play sand and coco-fiber in a large plant pot - works great! Also needs to be deep enough for her to dig - at least 1.5 her body length. (Luna had no interest in her tub either time until the day she laid). She needs to know it is there - they usually lay at night so you wouldn't know anyway. If she begins to dig leave her alone. I have a shower curtain over the front of Luna's door to help with humidity and when I want to give her privacy I cover the whole cage. You may want to cover with a sheet or towel.
Don't bother about food if she is not interested but make sure she is well hydrated and drinking. Have you been giving her calcium? I used liquid calcium (neo calglucon) since she wasn't eating. You can check with your vet or get it online.
Not sure if you followed but two of our fellow forum members had a difficult time with their gravid females. One had surgery and her recovery is still in question and the other had surgery and she died
Not to scare you just to let you know how tricky this can be. If she begins to do anything unusual check with your vet. So watch her closely but also give her as much privacy as possible other than water/calcium.
OK, so those are my thoughts - hope it helps!
