I have had several clutches of leodpard geacko eggs and I can't seem to get them to hatch I've been follow the insructions on incubation from a site called albeys reptiles but it seems my fertile eggs are drying out and dying so it seems humidity might be a problem. Can you tell my what your water perlite ratios are and such. I just feel like a goof not being able to hatch leopard gecko eggs.

This is from Mellisa Kaplan's site. I find her site very accurate and reliable if not overly cautious.

Incubating The Eggs
You need to strike the right balance between a properly humid environment and it being too wet. Combine 6 parts vermiculite with 4 parts water so that the vermiculite is just barely moistened. Without changing how the eggs were laid, place them carefully into the moistened vermiculite, half burying them in the medium. Place a small container of water into the vermiculite too to help keep the humidity up.

A second method is to cut a piece of foam rubber to line a plastic box. Pour enough water into the box so that the foam is saturated and water just covers it. Place small dishes, lined with dampened vermiculite or paper towel, on the wetted foam, and place eggs in the small dishes. Cover the dishes with a layer of dampened paper towels.

Once your egg incubation boxes are prepared, you must incubate them. A Hova-Bator, sold in feed stores for bird eggs, works well. Follow the package directions for setting the incubator up and adjusting the temperature. Any place where you can keep the eggs safe from being jostled or shaken and where you can keep the temperatures constant throughout the incubation period will work. You will need to be able to get into the egg boxes to check the water and add water periodically.

If eggs are incubated at 79 F, the majority of all hatchlings will be female. If incubated at 85F, you will get an almost equal number of males and females. If incubated at 90F, most will be male; at 92F, practically all will be males. Females hatched from these eggs are generally more aggressive than other females, and are generally considered unsuitable for breeding. If you are trying to guarantee a certain number of males, set up two incubation chambers, with one set up at the higher, male-producing temperatures, and the other at one of the lower female-producing temperatures.

Depending upon the temperatures used, eggs will hatch in 6-12 weeks, with the higher temperatures hatching sooner.

I use a layer of Vermiculite, then sphagnum, to produce moisture. I spray and heat as required. In drier species, I'll likely tone down the sphag and throw down less spraying.

Mind you this is for Crested Geckos but many egg hatchers, as it were, tend to use vermic or something similar as an egg substrate anyways.
