I've heard several different things on this topic, and I am wondering about different people's experience. I am not planning on doing any serious winterizing/insulation or running electricity out to my coop. That being said, I'm debating the need for solar lighting to artificially lengthen the day, because I want my girls to pay rent (eggs). I've heard that they won't quit laying altogether during winter if they've already started. However, mind have not started and I've ALSO heard that they may not start until spring if the days are short. Bottom line -- should I buy solar powered lights?
