Not looking good.. Deformed hatchlings

[Galaxygirl]

Our female that laid these eggs went off feed for about 10 months during the time we were breeding her. She lost a lot of weight and we thought she reabsorbed after her long fast. She surprised us with 7 good eggs, pretty small looking ones with one slug and a boob.

We turned off the fan in our incubator because the eggs were collapsing at day 10 for our clutch still due to hatch which was around day 19 for this clutch, but the temperatures never seemed to fluctuate, we didn't have any power outages, etc, so we're afraid this may happen again and we're not sure as to what the culprit is. Lack of air flow/oxygen due to the fan being turned off? No one knows and we don't know how to prevent this from happening again..

We've only ever hatched one other clutch and it was from the same incubator, same father, different mother. That clutch had the fan on but also didn't have issues with humidity so we were able to leave the fan on. We burped the eggs maybe once a week or less, took them from the mom the day they were laid, used cling wrap, really stumped as to what went wrong..

Overall it's been a heart breaking process so far, we don't want to euthanize the hatchlings, but it'll have to be done if they cannot eat on their own..

So far it looks like 4 out of 7 have it. A spider has pipped and I couldn't see well, looks like he has it as well but not as bad. Two more still in their eggs...

If it is some incubator issue, I am now very afraid for the other hatchlings from the other clutch and still don't know how to fix this issue. The probe for the thermostat is kept in the egg tub to ensure the inside of the tub is the temperature it's supposed to be.
