I've been searching for a while now and coming up empty. We had a clutch of four eggs. When the first one pipped, one of the other eggs started to swell. It was a perfect egg before. Within hours of the first egg pipping, the indentations totally filled out, and the white of the shell disappeared, leaving it completely transparent. At this point, the snake could be seen inside, perfectly developed, but motionless. The bloated egg continued to sweat, while the surrounding eggs remained indented and unaffected.

By the time the other little ones pipped, this egg looked like a water balloon, only minimally larger at this point, but hub cut the egg open to reveal a perfectly formed, same size as its siblings, but dead baby. Heartwrenching.

What happened? None of the eggs was pre-cut. The egg was fine. We candled them and detected movement in all eggs in the clutch before the first one pipped. Within an hour or two after the first pip from another egg, this egg just filled with fluid, rounded out, and did the things mentioned above.

The rest of the clutch looks fine, although they're still pipped. We're not messing with them unless there is a danger posed by the egg remnants from the bloated egg.

Any help is much appreciated.
