Eggs Dented at 31 Days?

[kouneli]

So I have 2 eggs that are currently denting in the incubator. They're at day 31. The 4 other eggs are not denting and the substrate still seems moist, so I doubt it's the moisture. One of the dented eggs was candled about 2 weeks ago with very good veins showing. The other looked like it was infertile.
Just wondering if this would be pre-hatching at this early in time? If so, why is the "infertile" one denting too?

I'm incubating at 83/84F in a homemade incubator made out of a styrofoam box, heat mat with thermostat, digital thermometer, bowl of water on the heat mat, and containing the eggs is a plastic pencil box with moist vermiculite.

You fail to state what species it is that you're incubating. Not all gecko eggs incubate under the same conditions. You need to be more specific.

Wow...completely forgot about this thread. Thought it was listed under the leopard gecko section at first, reason why I wouldn't have put in the species. But I guess not.

So...Leopard gecko eggs were what I was concerned about. The eggs that dented eventually went bad, though earlier at least one had veins. Fortunately, I still got at least one hatchling out of my first breeding season, and she's doing quite well.
