I have a 30 X 50 barn with a 10 foot sliding door on both long sides. It's always just been a run in barn, no stalls or anything. But because of the different feeding needs of my 5 horses, I'm going to divide it up into stalls. OK, so I have 5 horses........I could divide it into 6 stalls of 10 X 20 a piece and use one of the stalls to store food and bedding in or divide one side into two 15 X 20 stalls and the other side into one 20 X 20 stall with a small 10 X 20 stall to store feed and bedding in. I could put my two big geldings in the 20 X 20, my two small arabs in the 15 X 20 and my mare in by herself in the other 15 X 20. Either choice would leave a 10 walkway down the center with the doors on either end. Each stall would be made of 12 inch posts (big ol' suckers that I'm re-using from another project) and 2x12 boards. They would only be in there at night after they were fed and be let out every morning before I go to work. They have approx. 5 acres to run around in during the day. What would you do and why?
