a couple of weeks ago i was walking through some flooded timber and jumping alot of ducks. i noticed one thing that i think would help convince the ducks they need to be in that hole. MUDDY WATER!!!! Wherever there were ducks the water was muddy, no ducks the water was clear. TIP walk around the decoys occasionally and kick the mud up to keep the water muddy because i garuantee the ducks can see it when they fly over.
