My chickens began laying eggs last year, but they had stopped in October or November due to the cold. How do some people get their chickens to continue laying in the winter? Is it added light or food? How bright does the light have to be? I have heard chickens need 16 hours of light to lay an egg if I am not mistaken. What kinds of food have to be feed to keep them to lay eggs? My coop is shut at night, with no wind blowing inside. Some people locally have their chickens laying eggs, and I do not understand how. My chickens are about 10 months old and like I said, they have laid eggs in the past. Please help out!
