I had one hen who laid her egg on the coop floor but in the same spot every day. She was the first pullet to start laying, when the others started to lay they layed in the nest boxes, she was the only one that layed on the floor. After about 3 weeks she stopped laying on the floor and layed in the next boxes. I think she learned from the others. It's been about 3 months since I've had an egg on the floor..
