Others can advise you better, but I don't think it will be a good idea to leave mum on the eggs if you're moving the eggs to a vermiculite/water mix. I think the humidity/moisture required to ensure the best result for the eggs will be more than is good for mum's health (risk of RI and scale rot).She's laid in a cardboard box, if I cut it off will it still be ok? I have vermiculite here so can do it as soon as I know. Can i lift the box onto the vermiculite and leave mum on them?
