I hoped to draw up some plans soon, and considering that we live on what was formerly a dairy farm, some of the concepts might be hard to grasp. We have a building that was formerly a machine shed, turned free-stall barn, then machine shed again once we sold the cows in '08. The inside of the building is turned into an indoor arena, (we knocked the concrete out of course,) with horse stalls/storage along one side where the feed area that had head-lock things, (clearly have been out of dairy farming for a while,) and a concrete slab on the other side of the wall where the food was put. On one end, adjacent the stalls, is a three-sided attached lean that was used for cows that were within weeks of delivery. Here there is a automatic water already installed, and we plan to split the lean in half between hay and horses. I plan to have a sliding door between the indoor arena and this lean, where I hopefully will be able to enter/exit the pen. I would like to have some bars so horses are visible through here, but not reachable by other horses. This way, if I pull a mare out to work with he will still be able to see them, and I can exercise them and put them back. Plus, most of the riding we do, if not in the arena, is in the trails/field which can be seen from where this pen will be. All of the other horses are in our front yard nearest the road, and there will be several building separating them, and no shared fence line. We still plan on working our mares, and whether he paces or stands still is up to him. Our horses are bonded together in a herd, and do have a bit of distress when one of their herd is taken away, but they learn to deal with it. I know many things are different with a stallion, but this will be something he will learn to manage.
