So I get an BYC email the other day about winterizing the coop. It mentions to add a light (I forget what wattage) to mimic "daylight" in order to prevent forcing the hens into a molt. Then I read that having a light on will not allow the chickens to rest over the winter and will cause them to have a shorter life. So which one is it??? Light the coop to prevent molting? Leave the coop dark so they live longer? If lighting the coop is a good idea (since forcing a molt right before winter seems like a bad idea here in WNY), what wattage light bulb do I use?
