I'm fairly chicken ignorant, although I have 10 of the little beasties.
I keep a large hanging waterer out in the run, and a smaller hanging one in the coop. There's a dish of feed in the coop, as well.
I don't believe that my beasties are eating or drinking during the night, once they roost. If they're not settled in when I lock them in at night, they're mildly active, and will "snack" some.
I know that they are up earlier in the morning than when they're turned out from the coop, and I don't doubt that they are using the waterer and feed dish before they get out in the morning, And, when I lock them in again in the evening, the feed dish is empty and the waterer is lower and dirty. They use the coop feed and water during the day, as well as the run feed and water.
