I have a large old barn, with many rooms of the main part. We want to use one of these rooms as a coop for the chickens (14 Black Sex Link hens) with a door out to the yard. I'm confused about different set-ups I've seen. Some show boxes for them to lay in and others show roosts (not sure how high they should be) and pine shavings on the floor with a portion un-littered (presumably for laying). Also I'm confused about the 'hanging food and water'. This room is about 10' x 12' with two doors on opposite walls and two windows on one wall. We are only using them for eggs, not brooding if this makes any difference. Any and all info would be appreciated.
