I would not put feed and water inside. They have no motivation to come outside if you do. I have never had a chicken starve itself to death because it wouldn't come out and eat. I don't think your coop looks big enough to put food and water in there without ending up with a huge mess.
OP, it's plenty warm for them (@Ducks4us - OP is not n the U.K., so they are talking 5 degrees Celsius - about 41 degrees Fahrenheit).
