Have been hunting a local river, not one of the big 3. Each morning when we motor to our spot we see a lot of ducks (mallards) in the dark like 200+. Normaly we continue down stream to a weed bed to set up and may have a single or small flock decoy. Today we saw them again and about center of the large raft we split them and set up. Saw a few center of the river witch took off at LST and went up river. That was it except for a few mergs and if I can't eat them I won't shoot them. The area for this large raft of birds seems to be consistant so what should I do? Set up above them and hope to deek some in as they always seem to go up river when they leave or consider it a roost a forget it?
