I need to know more about lighting my coop when my days are getting shorter. Please don't bash me for wanting to keep more "daylight" for my girls. We got into chickens for the eggs. The economy is tough and the chickens are to provide food for us. That said, I take very good care of my chickens. I currently use a florescent small wattage light in the coop all night. I need to know what wattage I need to have to keep the days longer for them as my days of daylight grow shorter here in IA. I also need to know if I can use florescents or if I have to change the type of bulb I use.
