I use the coarse vermiculite to incubate the eggs in in shoebox sized plastic containers. I poke two very tiny holes in the lids of the containers. I fill them about half full of moist vermiculite. To test for the moisture level of the vermiculite, take a fist full of it and squeeze. If only a drop or two of water comes out it should be right. I lay the eggs in small dents that I have made with my thumb in rows space about 1" apart in all directions. This spacing will make the eggs hatch more individually. The container is only filled half full so that there is "head room" for the babies when they hatch. Put the lids on and place the containers in the dark wherever you intend to incubate them.
