Eggs are soft when first deposited but should firm up and expand after a couple of hours. Chuck eggs often show a little pink spot when first laid. This means they are fertile. I have sometimes had fertile eggs hatch and never saw the pink spot. Last clutch, the female didn't bury the eggs, but did put them in the vermiculite. On examination of the "birth chamber", I found a completely buried egg. All seem to be doing well. I have also had scattered eggs that hatched. If they are not firm the next day, remove them. They are not good, will rot, and will contribute to fungus on the remaining eggs.
