Hello, and welcome! Glad that you joined! Not all rooster's are mean. You don't really need a rooster unless you want to have fertile egg's for hatching. Since you plan to free range in/on a wooded lot or land, just because you have one rooster doesn't mean that your hen's can't be taken by predator's. Some predator's travel in pair's or even pack's and could overwhelm a whole flock. A rooster can only be in one place at a time.
