A little dent in it is that a bad thing? And if so what does it mean how does it get like that?
It could be caused by low humidity in the incubation chamber. If you are using vermiculite, the pieces should be damp enough to lightly stick together when pressed between your fingers. You may need to drip some water in between the eggs to remoisten the egg substrate. Don't wet the eggs directly. . Eggs will also appear to slightly collapse just prior to hatching.
