Leopard geck eggs

Question
QUESTION: Hello,
   I have two leopard gecko eggs. A few days after they were laid, I put them in an incubator and misted them every morning keeping the temp. at approx. 80. I was told that they should hatch almost 60 days right on from the time they are laid. It has been so far 63 days. A few weeks ago (maybe a month ago) the I started noticing the eggs getting bigger, and less white. They started to look a little bit more clear (yet you cannot see through them). I was told by a reptile lab owner that they look healthy. They are not shriveled at all, and they are bigger from when they were laid. Is this normal to happen? Why are they not hatching yet? Was I told correctly that they hatch nearly 60 days right on? Why are they near clear (they are, however, still a little bit white).

Thank you!

ANSWER: Hi Mitch,
It can take up to 12 weeks for the eggs to hatch, depending on the temperature.  The lower temperature, the longer til hatching.
Provided they are fertile, you are still within the time frame. Generally, right before they are ready to hatch, they will start to look a bit caved in. Right now, it sounds like all is normal. Since you are incubating on the low end of temperatures, it will take longer.

QUESTION: Hello again,

    Thanks for responding. I looked at the pictures and compared them to my eggs. They are about that size, however, they are not really that white. Is there a way to tell if they are sterile? What would the effects be if i turned the temperature up about 5-10 degrees? Would it affect them? (They have to hatch within two weeks from now because I can't keep them in the reptile lab any longer than two weeks from today) I know that there is really no definite way of knowing when they will hatch, but will it decrease the time it takes?

Thanks!

Hi Mitch,
You don't want to increase the temperature as that it will deform the babies at this point.  If they eggs were not viable you would know it by now as they would be dented, molding and not normal looking.
Hopefully they hatch before two weeks.  Just in case, I would make plans on a way to move them to another location safely.  Using a Styrofoam cooler and heat packs would be the best way.  I would test out the method prior so that you are able to maintain the 80 degrees you now have the eggs at. Again, do not increase the temperature now as it will harm the babies.
If your female was bred, and the eggs are still looking fine, don't give up!!! Much on the color of the eggs can vary with what is being used as the substrate for the eggs.
