I've noticed that mine will go back up for a little while during the morning, maybe for an early morning nap? but tend to stay out most of the day, even during heavy downpours or thunder and lighting, they dont seem to be frightened of it. Usually the only other times they go up is mid-day to lay, i've noticed. I wouldn't worry too much about them going into the coop or not. be sure to place a couple golf balls where you would like them to lay their eggs, prior to me doing that, they would lay eggs randomly throughout the coop. i only keep food in their run, however i don't keep their coop locked up at night so they can go down and get food/water if they need to, i've never observed them making a food run in the middle of the night though. If they have access to their run at night, i wouldn't worry about putting food in the coop, it just makes more work for you. hope this helps
