I have long been told that egg production is light dependent and as the days grow shorter egg production will wane. In keeping with this idea, I have always added a light to my coop during the winter months. However, I had never considered how this affects the hens. Does anyone know? Are there down sides to using a light? I know there are a few people on this site who prefer natural remedies, so is there a natural cycle to laying that should be observed with regards to daylight? I have not added a light yet this year but egg production has not slowed much despite it getting dark at 6:00pm. I keep a detailed record of eggs produced including hen name, time of day, egg weight, and egg circumference. Perhaps I will do an experiment this year and see how much shorter days really affect egg production. Does anyone know if this has already been done? Thanks!
