thats very bad if she letting them out over the the mulch that means the environment she is in is not providing what she needs to lay her eggs properly. Get her on some dirt, when i mean some i mean at least 2ft, there burrowing monitors and should be kept on dirt plain and simple. If you due not due this you may have a female that will get eggbound and die as a result. My female argus goes all the way to the bottom of the 2ft of dirt i have in her cage without a problem to lay her eggs every few months and i bet if i put another foot or 2 in she would go all the way still. please add the dirt as soon as possible and good luck with the eggs. Did the male breed the male breed with her or not?
