Ok she was gravid and has laid two eggs so far today, she also turned around and tried to eat the eggs almost right after she laid them. Is this normal and if not any ideas about the reason she would do this. All information is welcome.
Has any body ever used zoo med incubators, are they effective

I don't keep Gila Monsters, (Heloderma suspectum) but I keep a folder with hundreds of "care sheets" on my computer. This one seems to have some good info, and even mentions the egg eating. http://www.kingsnake.com/rockymountain/RMHPages/RMHgila.htm
Hope it helps, take care, Marty

Marty thanks for the help, I will check this site out. She laid another this morni ng and got to it before she did, and unfortunantly think the second egg she laid is fauled already. Appreciate the help!

Wow, she tried to eat them after laying them? That is the first I've ever heard of an animal, or reptile anyway, immediately attempting to cannibalize its offspring. You'd think some instinct would kick in and prevent the mom from acting that way.
I suppose we are dealing with a very primitive, basally instinctual creature though so behaviors like that shouldn't be too surprising.
Still weird though! Let us know if you're able to hatch any of the little ones!

Good luck on it and be sure to let us know how it goes. I am hoping to breed some heloderms later as well so thank you for the link marty.

Talking to Dr. Seward i guess in captivity it is actually common for the female to try to eat the eggs, so he said to take them as she lays them. Which is hard to keep that close an eye on the nest box unless thats all you have to do and don't have 30 other exhibits to take care of! But for the future that is a good thing to know. I however am not sure if my eggs are any good anyways already pitched one that was fouled not sure on the other two. Will be talking to people to see if I can go ahead and start the hibernation breeding process on the pair again or if I need to wait for a specific month.

Not that I have a lot of experience with Gilas but I have had Madagascar Giant Day Geckos turn around and eat their eggs shortly after they were laid. I imagine it is not that uncommon in conditions that are somewhat less than perfect - the mom will want to regain some of that body mass / nutrition that she gave up by developing and laying the eggs.

That all makes sense, though still surprising and interesting to me from an evolutionary biology standpoint. Generically, it would make more sense that the parent would sacrifice itself (there are many examples of this in other species) for the good of the next generation. Such a glaring example of personal selfishness gives me hope that maybe we humans aren't too far separated from our distant kin after all :)
