Eggs cracking in the middle

[BocaJan]

I have a clutch of veiled eggs that are starting to sweat, however they are cracking in the middle instead of the normal pipping that happens on the end. When laid, some of the eggs had a poorly formed shell and had to be disposed of. Could this be a problem with the calcium or would there be something else?

Its possible that you kept the eggs too moist. When this happens, what happens to the babies?

I'm waiting for more comments. So far I haven't touched the eggs. Should I try to birth the ones that are broken open in the middle? It is about time anyway.

are they turning a dirty green or orange/brown color? I had some turn that color then start to crack like yours are. Whole clutch was lost within a few weeks yet there was fully developed babies in the eggs.
