Get all your dekes out the more the better this is one situation I would recomend putting out everything you got plus borrow some more
I like to find a feild where the ducks are flying past or already going to,scout, scout, scout. If you can find a place where two feilds come togather say a bean feild and a corn feild (not really hard to find in Ne and Ks.) thats where I would set up because the corn is cut higher from the ground than beans so you can build or set up your hide in the corn on the edge of the beans. The reason I do this is because the ducks and geese will see your dekes from the air easier in the bean feild than in the corn. I set up all the FB and BF dekes I can get my hands on in the beans and set up all my water dekes shells and so forth in the corn. The birds will see all the dekes from up high but when they get low they'll be eyeballin the dekes in the beanfeild alot closer the the ones in the corn. Then all you gotta do is sit up and start hammerin GOOD LUCK!!
P.S. It's alot of work settin up all them decoys so make it a big shoot and take your friends so they can carry dekes for you hahaha.
Some days you do everything right and don,t bag a thing , Some days you do everything wrong and still get LUCKY !!!
