another thing about decoy spread is on the windy days duck tend to fly against the wind to slow down, so if your wind is blowing east ducks usually will come from the west for example. the thing about the big ducks they like to land on the outside of your decoys except teal will land right in em. so figure out the wind pattern set up your decoys not right in front of you but more to you left or right so that when the ducks come in just happens to be right in front of you.
