Yes, female. She has the tell-tale moustache of light coloured hair. The rocks could cause a problem if she burrows underneath them and they fall on her. Or, if she falls on top of them from the enclosure side. Her abdomen is extremely delicate.
@VanessaS Thanks! The rocks are sitting on a foam block (buried slightly beneath the substrate) to prevent the burrowing issue, and I put some soft plastic vegetation covering them in the corner/side where she might climb, but still I am thinking I will remove them (better safe than sorry!)
