Id suggest the following:
1. Don't camp and instead plan to say in a motel. It will be very cold here in December. Lows in the teens and 20's if you're lucky. Plus no daylight to speak of. Sun goes down about 5pm that time of year. Not hard to find motels that take dogs, at all. Savings in gas and wear and tear on your vehicle could be substantial.
2. Be somewhat flexible on your dates or locations. it could be in the 50's during the day or in the single digits. Sunny and calm or blizzard like conditions. If it looks unfavorable for your first choice, then you have a back up plan already made.
3. Our bonus birds are prairie grouse. The best time to hunt them is early in the fall before pheasant season opens.
4. I'd suggest you look at booking a wild bird outfitter, there are many including Daybreak, Halverson and ToriLil. You might find something you like from one of them. Easier to get birds on public in the days after the crops go out of the field. By December, depending on weather, many are utilizing private land exclusively. You might not see many at all on places you can hunt for free. YMMV.
Good luck and have fun.
