I am returning to duck hunting after a 20 absence. Have been spending more time bow hunting and fied goosing lately but want to get back into ducking with my 14 year old son. I am in Southern Minnesota. I use to hunt mostly West Central Wisconson years ago in back waters of the Chippewa River, at the time we never used deks as we were a bunch of college kids with a hair up our ascots. However, I am looking at getting set up with a dek spread. How many is a reasonable number and what mix of breeds should I use? What I am thinking is 2 dozen mallards mixed hens and drakes and a half dozen blue wing, half dozen green wing and half dozen Woodies. Would love you hear your suggestions and recommendations.
