We've been getting 6 eggs a day for over a year, but for the last month, maybe 2. We chalked it up to a broody hen being a snot; however, she was sitting on 7 eggs and everyone of them was gone this morning. My son said that he has seen them eat eggs and even some shells, but that was a long, long time ago. It's possible it's an egg snake, but we've seen no sign of one and we've been watching. Any ideas of how we can get to the bottom of this?
