1) How common is it for the white mark on a horse's face (I'm sure there's a name for it but I have no idea what it is) to be extremely irregular? I don't just mean asymmetrical, but genuinely crooked. Maybe starting on the far left side of the face near the mouth and continuing up over the right eye.
2) If a horse is in a stable in cold weather (say high 30's low 40's and drizzling rain) is the animal likely to go outside? The doors are all open, so it can go where it wants. Would it prefer to be out of the rain or out of an enclosed space? Or would it depend on the personality of the horse?
