Whole clutch died.

Only advice I can offer is to triple check everything in your bator is working fine. Even if it wasn't though, I think it would be hard for the egg to last as long as they did and then go bad. So I'd look for another reason... What was the pairing? Has the mother laid before? Is the father a first timer? Idk this just sounds weird. I have all my eggs in the shoebox from the Container store and I don't poke holes. I also don't open the lid every day to give them air. I have found they get enough as long as there's airflow in the bator.

My tubs are airtight. I open generally once a day

The female has laid before. Male has bred plenty of times. Though not with each other.

Don't know what else to check in the bator. Temps are same everywhere. Egg boxes closed. Vermiculite damp. Egg crate on vermiculite separating eggs.

Only ever lost one egg before and that was in the crappy styrofoam 2 clutch bator I used the first two years.

If its the bator I don't think they'd die AFTER pipping?

Also, every other clutch in there is fine.

I don't know that anyone will be able to tell you for sure what happened because there are so many factors involved. My own green egg did not seem to impact the others from what I can tell, but they haven't hatched yet so I don't know if they'll be viable.

I did recently read a post on another forum where they (I think it was Rich Macias) suggested that temperatures may rise within egg boxes as the eggs start generating their own heat, and that it could be the reason why people lose snakes so close to hatching.

Aside from that, and this is just me spitballing here for you to consider/research on your own, they could have been exposed to a mold, bacteria, or chemical that overwhelmed them when they hatched - maybe the effort of hatching made them especially vulnerable to it. Or maybe something went wrong while they were developing internally and it only became an issue once they hatched - like underdeveloped lungs or something.

So sorry to hear about your clutch going bad! I hope the others are unaffected. Hopefully someone else with more experience can offer some insight.

So sorry to hear about the loss hungba. It sounds like you did everything right. Some of these breeding and incubation processes are truly in the hands of the odds gods. Keep up your good work and chalk it up.

Are their bottom jaws fully formed? Our entire clutch hatched with an overbite. We didn't notice it at first, until we saw them flipped around. I know some babies with this deformity die shortly after hatching and it usually affects the whole clutch. It doesn't seem like an incubator issue if those two went full term..

[MrLang]

It's hard to say really. If they went full term but died after pipping I would think the 'green stuff' that killed the first eggs was still present in the tub and caused them to get sick and die after they opened their shell to expose themselves to it. That's my best guess... sorry for your loss.

What is your incubator temp? You said it's constant but what is it? Also, are you using just one or two thermometers to check it, maybe one is off? Too low of a temp can cause dead but outwardly perfect full-term babies.

Otherwise it may have just been that particular pairing that was the problem. I run my eggs the same as you, sealed plastic container w/ the Glad Press n Seal to maintain humidity at 99% or higher, and open the lids to permit air exchange briefly once a day for the last few weeks.

They had no physical abnormality.
