Im think about redoing my run and coop.Wanted to how much room do allow pre chicken? The size of the chickens are like Rhode Island Reds or something in that area.
These measurements can be adjusted depending on how much time your birds stay in the coop...warmer weather climates they would tend to be outdoors more....only in there run or free ranged, too...individual temperament, etc. But, you will seldom go wrong with the general rule of thumb.
