My RSL has been laying for almost a week. She had two good eggs in a nest box but now I keep finding them beneath the roost. I have two nest boxes for 6 chickens only 4 are laying yet. I added another nest box (yesterday) thinking that maybe she was either bullied out of a nest box or they were already occupied, but this morning I found her egg on the floor again. Does anyone have any ideas of how I can stop her from doing this?
