The last 5 eggs that my crested geckos have laid have gone full term and then not hatched. Around two and one half months the eggs will start to sweat and then about a week after it will start to shrink.

The first few I incubated in an incubator. Someone told me not to use the incubator and instead to just leave them out at room temp in a humidity box. So I tried that and that did not work.

They are on moist peat moss and are kept at 75 degrees. I open the lid once a day to air out the tuperware. What could be the problem? I give the females calcium supplement and a healthy diet.

It could be a couple of reasons. Diet for the female may be lacking something, check the calcium sacks in the mouth. Also make sure the eggs are not under calcified.

I did have a guy tell me that he had the same issue and he lost quite a few eggs and what he thought his issue was the eggs were harding or "drying out" on the top (unburied part) and the eggs were hardening where the babies weren't strong enough to slit the egg. I looked at him funny but he upped his humidity some and eggs from the same female started hatching for him so who knows.
