It seems that ever since daylight savings time, some of our chickens completely quit laying. We went from 8 to 11 per day down to 1 to 5. We lost a nh red a while back and it seemed like after that they just shut down. The EE hasn't laid an egg for about 3 weeks. I know the loss of one and them not laying is just coincidence, right? Is it the cold and loss of daylight? Will they pick back up if I put a light in the coop? Please help me!!!!!!!!!
