Mine definitely use the light in the evening to focus on the coop as daylight fails. I thought I had them all in one night but had miscounted and was one short. (Hard to count to 12 when they are moving around.) When I went out to make the final check and give goodnight pets (they love that!), I heard a little plaintive squawk from the nearby woods. I focused a light and a girl was SLOWLY moving in the darkness towards the coop, one little step at a time. I went out and picked her up and carried her to the coop. She was a very happy girl in my arms as we walked toward the light.
Plus mine are late night eaters just before they head for the roosts. They really load up before bed no matter how much they have eaten outdoors.
