happened to my old friend in PA a long time ago. His cat knocked his eggs off the refrigerator, and they scattered all over the floor. He came home at night, put them back in the container, back up on top, and months later, most hatched.
Very tough - but too much water WILL kill them. Kept in sealed containers, where minimal condensation forms on top (drops = too moist), and they're downright easy. The only reptile eggs easier to incubate are phelsuma (day geckos), especially the non-gluer types. Hard shelled eggs, put them in a plastic cup (pill bottles work), and in a cup with slightly humid vermiculite, keep them warm, they hatch almost every time.
Very fun little critters, I miss them... My brother has our standingi still. We've had our big female for close to 15 years now, and she was full grown when we got her as an import from Gulf Coast Reptiles. She's probably over 20 years old. They can live to be over 30. Crazy things... I know people breeding the tiny little ones (klemmeri) that have had the same ones for over 20 years, and they're still going strong. and these are things that eat 1/8-1/4" crickets and nectar - yet they don't seem to have an evolved a reason to die!
Everyone, you have to apologize for my often long-winded and tangental rants. I was laid off on the first, and I am bored and lonely - and there's only so much supreme commander I can play before my head explodes.
