My hens are probably a couple of weeks away from starting to lay eggs. The coop has 2 nest boxes, in which I've recently placed soft pine wood shavings (before they were just empty). I've never seen any of the hens get into the nest boxes, although they do roost on a post sticks out from the nest boxes. I've read somewhere to put fake eggs in the nest boxes.... is this true... does this work? Are fake plastic eggs what to use, or is there something else I should use? thanks very much for the help and suggestions.
