My friend has been keeping a female African Fat Tailed Gecko with a Leopard Gecko and they mated. She laid two eggs yesterday. The geckos then built a nest around the eggs with some moist moss!

I have told him that not only should he not be keeping these two different types of gecko together, but that he should probably remove the eggs and incubate them if he wants them to have the best chance of hatching.

Am I right in thinking that there are no hybrids of these geckos in existance? I have heard that the eggs are often infertile or the offspring are deformed and die within a couple of weeks.

Can someone reccomend a website with good info on how to handle and incubate the eggs?
