I built a new coupe to accommodate the four new hens and our existing two older hens. With the older ones, we had a very small coupe with two nesting boxes, and they would on lay in one, and it was a dark coupe without windows and only a vent hole, and coupe entry providing light. I made the new coupe nesting boxes the same size but made three. After I took away the old coupe, the old hens laid a couple eggs in one of the new nesting boxes, but have since stopped laying, or are laying outside in a nice tucked away area in our bamboo, along with the two of the new hens eggs. How on earth do I get them to use the nesting boxes? The new coupe has windows, and I painted the interior gloss white. Do they really need darkness, or is this just a coincidence? Any suggestions for us?
