I had one of my females lay a clutch of eggs just over 3 weeks ago. I have tried to candle them and they appear to be yellow. However, they have not developed any mold. Is there a chance that the eggs are fertile? they have been incubating at 82 degrees and are in vermiculite. Thanks for all of your help with my first clutch of eggs.

The same thing happened to me. One acted like it was going to hatch, and we finally opened it and there was just goo. My other one appears to be fine, but it is also yellow in color when I candle it. I dont know I am letting it sit in there until it hatches or goes bad.

These eggs are probably infertile. At three weeks you should be able to easily see the veins in the egg. I say incubate them anyway, just because you never know, but also don't hold your hopes too high. I don't think I've ever had a first clutch from a female be fertile. Trust me, as soon as she lays her second clutch and you candle them, you'll see right away the difference between fertile and non-fertile. Those first clutches confused me too. lol

Usually, you can candle eggs within 6 days and tell with near certainty whether they are fertile or not. I take them into a dark closet and put a flashlight under them. If they show veins or glow pink or red, they are good. If they are yellow they go into the trash. The fetus starts to develop within 2-3 days after the egg is laid, therefore 6 days is plenty of time before the first candle is done.

I almost forgot.... every one that I have had glow yellow has failed, and often, they lasted over 45 days before they collapsed. Just be sure they are marked and do not rotate them during candling.

Make sure you carefully mark the top of the egg for this... then get a flashlight and a dim room. I can tell if eggs are fertile right after they're laid and hardened doing this... Turn the egg very slowly while held over the flashlight... look for a red "bullseye" circle.. it'll be a light pink circle with a red dot in the center of it. Thats a fertile egg....Then make sure you turn the egg rightside up again... For the first week or 2... most eggs are internally yellowish.. it doesn't mean they're bad.. but if you can find that red circle... with the dot... you're doing well..

I would say they are probably not fertile, but incubate them anyway. I had 3 that were a yellowish color, and they didn't ever get mold on them, but about 20 days in they started to smell bad, and we opened them up two were like hard boiled eggs and the other was just goo. We just had my albino females 2nd clutch hatch one on Sat. and the other on Sunday, and that is what their names are...lol We will not forget their names....here's Saturday.
