I would start by not misting the eggs (this could cause excess moisture absorption and could attract fungus/bacteria). The perfect environment for gecko eggs is in a small tupperware container with maybe 4 little holes in it. Fill the bottom of the tupperware with vermiculite or perlite or both, and moisten this material with water(do not soak it just moisten it so that it clumps together when squeezed, but doesn't drip). Make an indentation in the vermiculite to secure the egg in its new home. Put the top on the tupperware with the egg inside laying in a crevice in the vermiculite, and store the tupperware either in an incubator set at 84 degrees, or if you don't have an incubator you can seal the tupperware and put in inside your lizard enclosure(somewhere where the temp is not too hot, like on the cool side of the cage.) Hope this helps. I'm sure you could also put the tupperware on your cable box, since the box is usually on and therefore always warm.
