About 3-4 weeks ago we had a week long cold snap -10 deg hens stopped laying. I had three heat lamps running 24-7 but We still lost a hen during that first week. Then about two weeks ago we ran into another cold snap for a couple of days but it was not as cold. Anyways from November, right up to that first cold snap, we were getting 10-16 eggs a day. After that cold week we have not seen any eggs.... Do i just wait or is there something i can do to get production going again?
