I would put my dekes in a more U shaped pattern and away from the blind on othe other side of the hole.. Ducks will land into the wind and will tend not to fly over ducks on water so that any ducks that leave will others are landing won't collide.. You should put your dekes where you don't want the ducks to land and so that as the ducks land into the wind and into the U shaped opening you have a good shot..
