So I decided to put a light in the coop because I'm so excited to finally get our first eggs (5 month old hens). I keep the food & water down below in the run to discourage rodents up in the coop where they roost. But now that the light is on, they're milling about with nothing to do! They're scratching aimlessly in pine chips. Should I provide food & water up in the coop, too?
