Temperature Helps Determine Decoy Set-Ups

Some hunters will set their decoys really close together when the weather is hot. That’s a mistake. Other hunters will set their decoys too far apart from each other when the weather is very cold. That's also a mistake.

I filmed a duck hunt in South Dakota where the temperature was in single digits for about three days. We had our decoys sitting really close to each other in what we called a tight decoy spread. On the fourth morning, when we arrived at the blind, the weather report stated that the air temperature would be about 35 degrees and then warm up to 50 degrees during the day. We left our tight spread set up for the first part of the morning, but we had a tough time getting the ducks to come into that tight spread. So, later in the morning, we got out of our blind and loosened up our decoys by putting them farther apart, and the ducks started coming in like we were having a blue light special at Kmart. 

If the morning’s very cold, and I’ve got decoys on the land, I may have those decoys within a foot of each other. I want to give the impression that those ducks and geese are staying close to each other to get warm. We can’t set our floaters (floating decoys) that close, because we want the decoys to move with the wind. So, we’ll set 100 decoys to make a spread that’s perhaps only 60 yards long and 25 yards wide. Tightening up or loosening your spread is much easier when you’ve got full body decoys or shells, and you’re putting the decoys on sandbars, mud flats or ice. You want your floaters to be able to move and not run into each other. 

Often, when we have about three inches of ice, we can crack the ice and create a killing hole out in front of our blind, while trying to keep the ice intact. Then we can sit our shells and full-bodied decoys on the ice to look natural. Another thing that helps us is that we’re hunting Canada geese and ducks at the same time. So, when we ring these holes, we’ll put full-bodied duck decoys and full-bodied Canada geese decoys out to make our set-up look somewhat like a roost. 

When hunting late-season ducks, decoy set-ups matter. Pay attention to the temperature and consider the size of your decoy spreads. Bigger may not necessarily be better.

Attracting Ducks with Crops
It’s a fact, that you can attract and hold waterfowl if you plant areas with specific crops. We really don’t refer to them as food plots when in regards to waterfowl, but in essence, that’s what they are. Ducks, just like deer and most other wildlife, are always in search of that next meal and once they find a good location, they will steadily utilize it until it’s either gone, the need for migration takes
