i would not rattle call or do anything. Just scout the area and find a fresh scrap. It will be pre rut and i love pre rut because bucks are fighting over thereterritory and want to see what kind of does are in the area. If you can find a fresh scrap sit on top of it because most likely they will check it within 2 days hoping its in the day time. But keep it as natural as possible. Try this it works for me. Good luck
