Here's a question for all you experts out there (of which I am not) I have been fortunate enough to have about 6 of my females lay eggs this year. They are not extremely old, nor extremely heavy. Probably about a year and 35 grams. However, I have "candled" some of the eggs, and none have been fertile. There is a chance I don't know how to properly look for a fertile leopard gecko egg, but I can definately tell a fertile bearded dragon egg from and slug. I have two males that have produced the same amount of eggs, so I find it hard to believe they are both infertile. Can anyone shed some light on my dilema? Thanks for taking the time.

I'm going to tell you what I see when I candle my eggs...The ones that are fertile have a pink or red glow to them, almost like a bullseye on the top of the egg. The ones that aren't fertile, I still put in the incubator, because I want to be sure. It's almost like a yellow glow to the ones that aren't fertile. Not sure if this helps you any, hope it did.

What, exactly, do you see when candling them? Red lines at all?

Either way, don't throw your eggs out unless they start to mold. There have been people who swear their eggs were INfertile, but they kept them in the incubator anyway and ended up hatching babies from those same eggs!

Also, were your leopard geckos 35 grams when you started breeding them? I know they can lose a lot of weight while gravid - I've had some of my mine go from to 50 grams to 35 or so grams while they were gravid, just because they refused to eat.

Safety Tip: Don't breed them until they're at LEAST 50 grams - you want to have the extra weight because most leopard geckos will drop a lot of weight while gravid, and, at 50 grams, you have plenty of breathing room. (I'm writing this for any readers who don't know).

The eggs that I think are not fertile are in the incubator, and so far they haven't molded. They have been in there since April 15 incubating on 88 degrees...They are starting to dint and turn colors, but no mold. Just wondering how long do they normally incubate when they are at 88 degrees?
