Put four of them in the egg box, and fill the box up with perlite until it's even with the top of the spacers. Pour in a bunch of water until the water level is just a little bit below the top of the perlite. Put your eggcrate on top of the spacers, and your eggs on top of the eggcrate. The eggs are out of the substrate so you don't have to worry about it being to wet, while you still get all the humidity they could possibly need. About the only possible way to screw up this method of incubation is the temperatures in your incubator spiking too high.
That's how I set up my tubs, with one difference, I use hatchrite, add water and a light diffuser. Helix set at 89. cover with press and seal snap on the lid. Open it once a week to vent.
