I have 4 hens. They free range all day! The only time they go in the coop is to lay or roost. I have added a light outside my coop attached to the tree shining into the roost. Is that enough light? It is bright enough to see the chickens inside the coop. Does it have to be extremely close to work? My run is all wire. See picture of my coop. We are located in Alabama and currently the light comes on about 3:30 and it gets daylight about 6:40. And dark again at 6. Thanks!!
