I have been finding cracked eggs in my nest boxes lately. I had a terrible time with egg-eating so I talked my husband into building me some roll away nests. That has really slowed down the egg-eating but now I am finding cracked eggs in the box. (I am still in the training stage--removing small amounts of hay daily so the eggs don't all roll away like they should). I am wondering if when the egg is laid the hen stands up somewhat to drop the egg do they hit hard enough to crack but not break???
