Recently bought a hen who was laying on 7 eggs. They all seemed to be various stages, some looked very close to hatching, and some much earlier in development. We think the 2 that we’re much further along hatched and she ate the babies. We found the bits and pieces of the shells but no signs of babies. We moved the remaining eggs into an incubator. We have 1 that seems to be very close to hatching. We’ve left it alone, went to look at the eggs today and the very dark one has a crack. We’ve never hatched before so I’m not sure if it’s normal or if it’s a bad egg.
