I kept my hens in their pen for several weeks till they started laying in the nest boxes regularly. I have on only 2 or 3 occasions, found eggs in the middle of the pen. After molt, when they all quit laying, I found 3 eggs in a nest in the driveway garden, and then another time in the leaves under the bumper of the truck. After both those discoveries, I kept them penned for about a week, and then they all started laying in the nest boxes again. I do look around where I see them scratching, especially when egg production has dropped. Those "hunts" have been unproductive. I got 5 new layers about a month ago, and kept them in the usual week. I found a few eggs around the area where the pen is, but since I've started feeding them Cayanne pepper, they have all been laying in the nest boxes. I'm told it's an old wife's tale, but with the increase in eggs I've seen this week, I'm a believer!
