I have a golden comet that refuses to use a nest box. My nest boxes are standard size, dark and filled with pine shavings. My other hens use them without fail. The golden comet lays on the suspended chicken wire beneath the roost. My coop has a single roost that is 18 inches above chicken wire so manure will fall through to the ground. It is exactly the kind of situation one would place a hen in to break her of broodiness. It is bare wire, open at the bottom, well lit and cold. At first I thought she was dropping an egg every night from the roost but since have caught her at in the middle of the day. Anyone had a similar experience?
