Thanks everyone for all the fantastic advice that you all contribute. Below is the plans for our new chicken house which is located on the rear side of the barn. It's roughly an 11 x 26 foot room which will have attached 8 x 20 foot runway area for the chickens. It's basically a two section divided room with a storage area when first entering from the side door of the barn that opens via door to the 'main' chickens retreat. A heated brooder room is also near completion. A separate coop has been installed on the back wall that will be used more for winter which has a roost and more hen boxes. If you see something that might need be added to help out please post in reply any ideas. All help is greatly appreciated. Thanks!
