I try to go out a day in advance and scout to see where the birds are. Don't do any hunting then. Use a locator call to help find them. Look for sign like feathers, torn up ground, etc. Maybe you could see where they are roosting. Since this is your first hunt, why not try to set up in advance where you saw them hanging out the day before? This might be more successful than trying to chase them down just before dusk. Just get out well before daylight and set up your blind in and amongst trees but set your decoys out in the open, about 10-15 yards from your blind and wait for them to come in. Try to get set up with the sun behind you if you can. Good luck!
