The joke of sleeping in, was directed toward us the chicken keepers, not the chickens. If your feed and water are in the coop, that is fine. I personally like mine in the run so that the waste (food, water and poo) is kept out of the coops as much as possible. You can have feeders and water...
You don't HALFTA! Hens aren't drinking & eating at night. Be sure they can get to water & feed though at first light. If hey are locked in a coop that you have to open to let hem out there should be NO SLEEPIN IN though.
