I have gotten my first batch of eggs from my breeding pair of geckos (an albino and a blizzard). My friend has told me of a homemade incubator consisting of a critter keeper filled with water and a tupperware container that is held inside of the container that holds the eggs. There is then a submersible heater that gets the water to the temperature that I want. Well... I do not know how to tell if these eggs are fertile and I suppose it doesn't help that they are coated in the brown eco earth substrate (same as bed-a-beast) that I had in their humid hide. So... is there any way to clean the eggs and to tell whether or not they are fertile? Also.. I noticed them in their hide today and they seem a bit still instead of leathery (as I expected them to be). Another thing is that the top of the eggs seem sunken in. Are these signs of the eggs being infertile? I just need some help on judging the fertility of the eggs. Thanks for any help that is given!

Hello there,

You can check to see if the eggs are fertile by lightning the bottom of the eggs. In other words, go to a dark room, hold an egg by its hemispheres and then put some light under the egg. Once you have clear vision of what's inside of the egg, start rotating the eggs (still while you hold them by the hemispheres) whenever you see an orange circle, that is the embryo, which mean they are fertile. Good luck. Hope this helps you...

i would incubate eggs regardless and only dispose of them if the have caved in and molded over..when placed in moist vermiculite or such they should swell.. if they are infertile eggs tend to go vbad quick although a few eggs might go a lot longer before showing any signs.. like i said incubate intil they go bad
