I have my food and water inside the coop. The girls come back to the coop several times during the day, for food and water. When they come in to roost at night, they definitely all fill up on food and water, before they get on the roost. They also get up very early to eat and drink, before the door opens.
I don't think they get up to eat or drink during the night, though. I can't really see anything after the light goes out, but I know it's very quiet during the night. I like to keep the sound turned up on the coop cam, in case there's any trouble in the coop.
When we used a tractor for the pullets during the warmer months this year, I think their behavior was similar. Their food and water was in the covered run portion of the tractor and there was an open doorway to the housing area where they roosted. They just ate and drank in the run area, before going in to roost.
