This is my first time breeding leopard geckos. The first two eggs were duds as they molded and started to smell after only 3 days of being in the incubator. The second 2 I got are good. They have been incubating for 2 weeks now and I can see the pink in the middle of the eggs which I've heard is the embryo. Another female just laid two more eggs and they are really thin. I know they get plenty of calcium and a varied diet. Do you think these are infertile as well? I went ahead and put them in the incubator in case they are fertile. If they lay infertile eggs will they always be thin? or is there something I can do to save them?
