Zero eggs out of all six of them. They went from 6 eggs a day most days to none. Can't figure it out. Today was the third day. I haven't changed their food. Their light is on 14 hours a day and has been since the days started shortening on their own. Water available to them all day. Just BOOM. No eggs. I don't know what moulting looks like but they all look fine and would they all moult at once anyway? I checked that nothing could get into coop and get the eggs. No footprints around the coop so somebody's not stealing them. I'm lost. Any ideas?
