Two of my gals started laying just over a week ago. They would lay in the run even though I put golf balls in the nest boxes. After the 3rd day of laying in the run, I talked with another chicken owner and he told me to remove the golf balls and lock them in the coop for a day. So I took his advice and locked them in all morning and afternoon. Let me tell you...they WERE NOT HAPPY! My daughter called me at work to tell me they were very upset and making a fuss. When I got home, I checked the nest boxes and found 2 eggs. Let them out into the run and they have been laying in the nest boxes ever since.
