besides the eggs wouldn't hatch because they weren't fertilize by a male :I it was just because she was eggy, that happened once to me lol kinda funny then pretty worried (the female died the next day )
What I'm guessing is that when sick and stressed, a female may lose control of her reproductive system and drop her eggs right before she is about to pass. Similarly, in mammals, sometimes when an animal is about to die, it will lose bladder/intestinal control.
Females cannot die from eating unfertilized eggs, it's always an underlying cause.
Females CAN die if they become egg-bound, or are unable to release their eggs.
