It'll be difficult to monitor the eggs in that set up. You also risk mom deciding to eat the eggs, and yes females will sometimes tend bad eggs but yours sound good. You also risk mom eating the babies once they hatch. The eggs are fairly resistant, just dig down to them carfully and remove the mother first.

Place them in a container with damp vermiculite. One part vermiculite to .8 parts water by weight will work best. If you don't have access to a scale, you can get the vermiculite wet and then squeeze it to remove as much water as you can and use that. The vermiculite should feel damp but not wet. When removing the eggs, be careful not to rotate them and bury them about 3/4ths so that the top is still exposed. Put them somewhere where the temperature is relatively stable. Do not put holes in the lid. Check them weekly or biweekly to remove any bad eggs and give them some air exchange. The eggs should hatch in 1 and a half to 2 months depending on temperature.
