We've got 2 first year layers that have decided to start laying very early int he morning before the sun comes up. And they're laying on the floor of the coop & 1 egg is always broken. Thought it could be that they couldn't see good enough to get in the nest boxes, but they're doing their thing on the floor & then going back to their hi roost. They'd been laying during the daylite hours for the first month or so. Have they turned into night owls?
