most of my first time females i would say over 90% laid good clutches there first lay. but some didn't. it all depends if the male got her at the right time.
2 first timers right now. First female with first 2 clutches infertile und second female 1 egg fertile one not(at first clutch). Third first timer will lay in the next week I guess^^
My only females that have laid up to this point have been first-time girls. The first clutch hatched from the first girl (so was obviously fertile ) and the first clutch laid by my other girl is looking fertile when I candle them so far.
The first 2 clutches that our little female laid were infertile but this was due to the fact that she was very underweight and should not have been bred. We have her up to 61 grams and she just laid her 3rd clutch 11 days ago and they look good. I candled them and both are fertile. I think it all depends on the health of the gecko.
