Right, so on a full horse-sized scale, I'd like the stall fronts to swing out completely to make the stalls more versatile (use aisle to convert a regular sized stall to a foaling stall, for example.) Aisle would be dirt, each stall would have an exterior dutch door, too. Each swinging front would be 100% mesh for ventilation for foals. Dutch doors would be mesh too, but exterior walls would be solid with ventilation high up. Would have swinging fronts on each end of the barn aisle, too.
