No not always. If she was with a male and could have bred then the eggs could be fertile. The wrinkling may be because the substrate they were laid in might not be moist enough. What I would do take eggs and put them in a container of moist vermiculite and cover them with the vermiculite as well. give it 2 weeks then candle them and see if they glow pink or have any veins which is fertile or if they are white then they are infertile. I always give them a chance.GL hope they are good ones
