one of the nicest things about keeping the horses in a natural manner is the way they become friendly towards humans. With little to fear other than being wormed or trimmed, they soon decide they like you and rush over to see you whenever they see you arrive in their fields.
It's very flattering to be greeted and surrounded by twenty plus horses (can be intimidating, you have to keep your wits about you too) all of whom are simply coming over to say hello..
