I have 37 pullets who are starting to lay, and we are getting 7-10 eggs a day right now from our birds. However, they will only lay them in one nest box. Not even the best nest box, in my opinion, as it is in a place where sometimes rain gets in, but it's the only one they'll use. It's become a problem because three birds will all manage to pile into the box and sit on one another, crushing and destroying their eggs. How can I encourage them to venture out into the others?
