Sometimes its really hard to tell what will and won't hatch. My 2nd clutch (without reintroduction of the male) included 16 eggs. All but 6 were obviously slugs. I really thought those 6 eggs were going to be fine. They were really nice looking. Now at 3 weeks, all have softened and started to collapse except 1. That one egg has some lovely veining in it, so I hope momma's efforts weren't totally wasted.
Good luck with your eggs. It will be really interesting to see what happens.
