I have 24 hens. 3 are 18 months old, the rest are 5-7 months old. Daylight hours are decreasing and with the light the egg production has been cut in half. I put a light in the coop. It's timed to turn on at 3 am, giving the hens 16 hours of light. The light has only been in use for the past four days, but so far I haven't been able to tell the difference in a production. Is there a special bulb you use? Do you supplement a special feed in the wintertime? What are some other secrets that could help them keep up their egg production? These are all young hens. Some of them aren't yet laying.
