Bill, Eggs either did not hatch or they were preemies (yolk still attached). How large (grams) are those cresties that you raised up?
Anyway 82F is not that far away from 80F, so there is still the possibility for problems, it is only 2 degrees away. I just honestly do not think it is an ideal temp to incubate. After all even an adult crested gecko does not favor those temps for long, an egg is even more sensitive. Incubating between 70-77F at least gives you a buffer if for some reason it gets to hot. Cooler temps are much more survivable then hotter ones. -Mike
