Viper Gecko laid eggs

I love viper geckos, I used to have a small colony of them, unfortunatly I didn't do very well at propagating them. I got a number of fertile eggs the first year but was never successful in raising the babies, they look kind of like a grain of rice with legs. I was feeding fruit flys, and they seemed to be eating fine, unfortunatly I was never able to keep one alive past about 2 weeks. The following year my adults gave me another pile of eggs, but none of them turned out to be fertile. The following year I didn't even get any eggs. My adults only lived to about 4 years. They are very cool little lizards though, a lot of personality in a small package.
