Nest boxes sharing is normal and expected, but 3-4 hens per nest is a recipe for broken eggs, egg-eating and pecking injuries. The stress of competing for a nest is also likely to put the kibosh on egg-laying for weeks- I knew that to avoid these problems I needed to add more temporary nest boxes than the one I already had on the floor of the coop. So, I resorted to what any self-respecting do-it-yourselfer would do in this situation: I took a trip to the local landfill for inspiration.
