I hunt that area a lot, private fields as well as the McHenry County Conservation Districts waterfowl program. Birds are in the area but very few migratory, a lot of local birds and way way way to much available food. First week of season they were suckers, not anymore. I suggest big spreads, flagging and decent calling. By big spread I'm putting out for just me 50 full bodies, 80 shells and 2 dozen socks plus my field mallards. Last weekends snap brought a few new birds into the area but not all that many, same with ducks. If you have been scouting and seeing birds then I am sure you are seeing the same thing I am, large groups 15-20 birds few or no singles/pairs. I think your best bet for this area is numbers, whatever you think is enough, double it. That and pray the cheddar heads get socked with snow.
