female corns producing eggs without a male?

[MPenn]

Yes it's possible for a female to drop an unfertilized clutch. Some females even though they've not bred but are of age /size still create follicles and will carry them to the point of being an egg and then lay them. But most unbred or never bred females will reabsorb the follicles.
Hope this helps.

This is all very true and plausible. Remember that female chameleons are known to develop eggs without the presence of a male and become eggbound. That is why most that are sold as pets are males.
A male is needed to fertilize the eggs. If the corn is never with a male, they will be infertile.
