I thought since I only have 4 hens they would share a nest box. That is not happening. One gets in there in the morning and hogs it for a while and another lays her eggs off the pirch so of course they crack. I've seen her using the nest box at other times so I'm guessing it's just because the other one is hogging it that she lays her eggs off the pirch. The othr two I don't think have started laying yet.
