When-
I guess I gave too general of info in my first post. Hunting Geese should be done in the morning right after sun up, they tend to fly when the can see, unlike ducks. They will go to eat then fly to water to sit on all day, then two hours before dark, (It will be like 7:26 PM today) so you want to be in position by 5:30, they will go eat again. You need to be in position by sun up or two hours before sun down. So that covers the hours you need to be in the field.
Decoys-
You need to have a mix of feeders to sentry(guards) set 90% of them with their faces into the wind, the geese take off and land into the wind like an airplane. I usually use an 80/20 mix of feeders and sentrys. the guard decoys I will face away from the wind in a random fashion. A good first pattern is to set the decoys in a loose horseshoe with hole of the shoe into the wind. You then lay in the open part of the horseshoe and the birds in theory will come and land near you with the wind.
Calling-
Just practice alot, you don't have to call a ton if you are not good. Just give a few clucks to grab some attention and to get them looking at your spread. Flute type calls are easier in general then short reed calls. Get one with a CD or tape and practice.
Killing time!
I tend to use size BB 3inch shells, make sure you got non toxic shot and have your gun plugged to only allow for 3 rounds in it. The DNR is real serious on those rules. You can kill geese at around 40 yards with the correct choke. Geese are hard to kill, they can take a licking. To kill them in hand, I normally ring their necks, or I have delivered a buttstroke before. I try for a fast humane kill. Make sure you try you best to get birds you cripple. Be sure to slit your tag before handling the birds, its a stickler rule. Search the net on how to field dress em.
So if I were you today (Sept 2)
-I would go to tichigan at 5.
-Drown myself in bugspray, get the stuff with deet.
-If you have decoys find the large field and spread them out.
-Pick out a spot and get ready to wait for most likely nothing.
-lay on your back and watch the sky, call when they get about the size of a dime in the sky
-Don't move, when they get close enough, shoot
-Be sure to be packing up 5 minutes before close time and have all the stamps/permits you need since the DNR often comes to that place to check closing hours.
That was a down and dirty guide to hunting geese today, feel free to ask more questions of me if you would like. I live in Franklin and hunt all of SE Wisconsin. To be honest, I won't take you hunting but I can tell you how to do it and where. You will have little to no luck this early season, but the regular season starts soon and you might learn just enough to have some birds down then.
Any Questions let me know
