I had a jungle carpet python egg go bad a little over a week into incubation and wound up cutting it away from the rest of the clutch. I found a solid mass and what might have been a tiny embryo in that egg. It made me feel awful as though I could have prevented it and didn't. I know that's not the case, but it doesn't make the loss much easier. I'm sorry those two didn't make it for you. Keeping my fingers crossed for your other three.
