I have heard that you need to put a bowl of sand at the bottom of the cage for her to lay her unfertilized eggs, but I have also heard that sand could hurt her if she accidentally ingests some of it. Someone has also told me that breeding her once when she first becomes mature can help the unfertilized eggs not to become a problem. I really am not in a position to breed her, I don't have the time or money for it, but I really don't want to risk her health either. HELP!
