I have some led christmas lights that I am going to add to coop to get these seriously late bloomers to lay. I am late in doing this as I wrongly assumed that production layers that are in their first year of laying don't need light(obviously I was wrong lol). Anyhow, days are 10 hours now. My Q is... -do I need to gradually increase light? An article at the chickenchick says to do it in 20 minute increments each week. A purdue article says to do it in hour increments each week. -is it necessary? How much stress would it be to go cold turkey and start turning light on 4 hours earlier?
