I don't know why I didn't think of this before. I had an extra nesting box sitting outside the coop on my little utility cart, but I hadn't put in any nesting material. I also noticed that the girls used only three of the four nesting boxes inside the hen house.
Given that the girls did find a way to lay eggs under the utility cart, I wondered if they would use nesting boxes on the cart. To test my theory, I took out the extra box and set it next to the box on the cart. I then added some nesting straw and one wooden egg to each.
