I incubate cracked eggs, and have had success... different set of risks and possible issues than a double yolker... with the cracked ones they're just dead if something goes wrong, not malformed and alive.Well, here is an egg with a crack in it, most would say don't try and incubate this, but here it is, with nail polish on it it is on day 6.View attachment 1232863It is in it's own incubator, it was a shipped egg that was fine, then it got dented when placed in the dividers in a diff incubator. the egg is a rare pavlovaskaya egg and after WW2 there were only 2 of these kind of birds in Russia. So I am not, not going to try and hatch.
