Chickens can't see in dim light so once they get settled on the roosts in the evening, they stay there until there's enough light for them to see again in the morning. They don't get up for a midnight snack, so it's okay to not put food in the coop. My chickens also free-range during the day and only sleep and lay eggs inside the coop. I have a hanging waterer with nipples inside the coop so they can get a drink in the morning while waiting for the lazy humans to get out of bed and open the doors. The hanging waterer eliminates spills. I have a metal trashcan that I put the feeders in at night so critters don't come eat the food. I like the chickens to have water available because it can be a couple of hours between them waking up and one of us going out to open the doors, but if they have to wait for food, that's fine.
