You will find many droppings in a roosting area. Go out before dark and roost them, then you know where they are the next morning. Sounds simple right,,Just amke sure you don't get to close and spook them while roosting or on the roost,,Look also for scratchings on the ground where they have been feeding,, Kinda looks like a small buck scrape,,also keep your eye open for dusting bowls they make while they dust themselves in sand or other very loose dirt like sand. These are just a few signs to look for but usually the most obviouse to find,, Good luck,,J
