Mine had eggs in her for over 4 months, but she was egg binding/egg bound. Mine spent two weeks digging a "hole" that turned into the whole back half of her cage had zero substrate, she was down to glass yet still was going at it. It was just one hole in each corner, turned into a ditch pretty much. I'm not exactly sure what they should be doing after they dig a hole...surry I can't help with that. Mine dug for 2 weeks then let every single egg go at the top of her cage, staring me dead in the eye till I left the room to do some work.
