Being from GA, you can get away with less sq ft in the coop because the winters are not that bad, The food and water would have to be in the outside run, which is ok as long as you can keep the food dry. The roosts are a little restrictive for large fowl due to the lack of height above floor level . I see this as the main problem. Also, if you were close in the area under the coop, it gives you more than enough space out of the weather. As long as you make sure it stays dry . You could underpin with tarps or tin during the winter months and open it during the summer.
