Plenty of daylight these days, but I've debated adding lighting to my coop for the shorter days to come. I live in Northern New York so winters are plenty cold. My reasoning in not lighting the coop to extend "daylight" hours was that in forcing the hens to produce eggs I would be robbing them of energy they need to comfortably weather the winter. Am I wrong in my assumption that their production drops off as the days get shorter because shorter days mean colder weather, less feeding hours and they need to conserve the energy that would go into egg production to survive the winter better? Would my "forcing" them to produce compromise their ability to thrive during the winter? My coop is insulated and tight but unheated, yet the chickens do well throughout the winter even in temps. well below zero. Never lost one through 4 winters. Also, as the potential amount of eggs they will lay is predetermined, by dropping of production through the winters will they lay for more years? I've got 3 year old pullets that still lay with decent productivity through Spring/Summer/Fall.
