i have a broody hen that had 6 eggs under her over two weeks ago. She has her nest in deep pine shavings on the floor of the coop, which is very secure. I marked the eggs and decided to let her be. Everyday I have checked her, and many days she would have a new egg under her but also one of the marked eggs is missing, totally missing. It’s not like it got broken, there are no shells, no mess, no nothing, anywhere in the coop. She is now down to three of the original marked eggs. What is happening to these eggs that go totally missing?
