Today I checked the nest boxes at the exact time one of my Red Stars was laying her egg. I watched her squat down and lay a broken egg, which her best mate immediately scarfed up. I grabbed the shell, took a pic, and disposed of it. This kind of solved a mystery, as each day for a while now, there has been a wet/yolks spot in that nest box, yet other eggs there are fine. And now that I think about it, we had gotten quite a few soft shell or thin, sandpaper shelled eggs this same color -- I assume hers. How can a hen lay a broken egg? And what should I do about it? They eat regular commercial feed and free-range.
