I found a cracked egg tonight under one of my momma hens. I'm not sure what happened but it was clearly born too soon and had passed away. The hen had some dried yolk and goo on her beak so its hard to say what happened. This batch of eggs should hatch sometime on Tues or Wed next week. I set them on the evening of 4-2 I'm kind of bummed because I just candled the eggs the other day and saw movement in there. Two eggs clearly had something going on, and I bet that my broken egg today was one of the ones that was OK a few days ago.
