if you can get into the same feild you should be good to go. total concealment is number one priority!! set your spread up away from the houses and work on some calling tactics but early season birds you dont need much calling at all especially if you are on their food source. now if its just one flock of birds coming in to the feild to feed it'll be tougher but if you have a few different groups hitting the feild it'll just appear as the first flight in found a bit of better food. the birds already feel safe in there so you just have to slide em out a little bit. you dont have to have them coming in and landing at your feet, if the birds are hitting the feild and its just one flock you will probably only get one shoot on em so set the deeks up where you want the birds will already be coming in low, but with a few deeks and a "couple" comfort welcoming clucks you can get them to swing in and at least check you out with in range. on the first pass if the birds seem as if they just wanna check you out and still hit the usual spot i would grind on em, if they are showing that they are in there and ready, yea shoot em like the "big boys" on t.v. but i would grind em on first pass....one flock of urban birds.... your gonna get one shoot 4 days later you might get another shoot if you grind em and get out quick. scout!! make sure its just one flock if not things will be easier for you and your buddies.
