Of the two didn't hatch one was an early quitter, so there was fluid. The one that failed to pip had some unabsorbed yolk, but nothing I would really describe as fluid beyond that. I have a Brinsea Mini Advance. If you're not familiar with it, it has a well in the center with two halves. You're supposed to keep half filled until lockdown, and then fill the second one then to increase humidity. It's supposed to be that easy.That humidity would be too high here and the embryos would die. Did you happen to eggtopsy the ones that didn't hatch last time? Was there liquid in the egg? You might try running it a little lower. I have to do 30% for mine to hatch.

I'll put the hygrometer in there tonight and see where I'm at. I'm guessing it's around 45%. You and I are both in New England, it looks like. The humidity outside is currently 71%, but I'm guessing it's far lower than that in my house with the heat on.
