Eggs gone bad?

Hello,

I have a clutch of 9 eggs which is just two weeks away from 60 days. Last night when I opened it to allow air exchange I noted a rotten egg smell. It seems 1 or 2 of the eggs may have gone bad. All of the eggs previously candled good with veins. Last night when I checked they seem to be yellowish but still some veins. Normally I know if an egg is not fertilized it will go bad within a week or so, but not this far along. I am incubating with a modified wine cooler and herpstat at 89 degrees. Should I be worried about the rest and try to remove the two eggs or leave them alone? I'd hate to lose the clutch this far along.

Thanks

Some pics would help, but it sounds like a baby may have died in the egg.
Being that far along something may have happened to the hatchling, tangled umbiclus, severe deformities, maybe drowned ,who knows.
If your certain you know which eggs are causing that odor then I suppose you could remove them and cut them open to see what happened or if they are still alive perhaps.

I will post som photos tonight. If they are bad, is there a good way to remove them? They are all stuck together. The two I suspect are bad are on top.

If they are stuck together, then I would just leave them alone as long as there isn't any visible rot that could transfer to the other eggs. But, as stated, pics would help.

Even without pics, it sounds very much like what I had last year with my pin x normal clutch. Ended up with two hatchlings dead in their eggs (one would have been a nice little pin).

Here's a pic. Looks worse now that I think about it. Any thoughts or suggestions?

Has this happened to anyone before?

Is there a buildup of condensation on top of the lid dripping down on the eggs at all?

Yes. There is condensation build up. When I put the tub in, it was on a very slight angle so the condensation would run off on one side. But I guess it is possible the got dripped on. I've placed something over the eggs now to avoid any more drips. What are the chances these guys will go full term?

just a guess ...

When you do substrateless incubating you want air holes or you need to mix the water to substrate mix 50/50
or you get too much humidity.
To me it looks like the humidity was too low and to compensate you added too much water for the tub.
If a tub has a way to ventilate then you'll never get too high of humidity.

They might hatch fine still, but I'd work on your egg tubs for future clutches
