Cold frosty clear mornings they will go water to water normally. You can sometimes break a bird or two off and get them to slide past a good field spread but I wouldn't count on it on these mornings. So, they will come off a roost and fly to a "loafing" pond which can also be a roost incidentally-or a golf course. Your only hope is to hunt the water they're going to or any small pond that is a loaf and try to work birds off the flight line. So, this leaves the afternoon feeding flight for a field spread which of course may or may not occur prior to sunset.
Cloudy days, days with any kind of precip they'll hit the field sometime before lunch usually and many times relatively early. You have to pattern geese and it takes time. Normally in the early part of the season they will always go out in the morning unless its very frosty. Then they'll normally make an afternoon flight unless its sweltering. As the season progresses they'll shift to a "one a day" or "two a day" feeding system. It all depends on the weather...temps, snow cover, the roost, hunting pressure and probably most importantly body condition. Lots of times geese will just go out from a roost and "ride around" as my buddy Dan puts it. Occasionally they will skip a day or even two before they make big feeding forays into the fields. This can be very frustrating If they are well fed and comfy a good time to hit them is 12-24 hours prior to a big low coming in...they know its coming and they'll try to hit the feedbag hard.
Non-local geese...predominantly the "interior" race in our case tend to feed more consistently and fly a bit earlier and in larger groups than the resident "giant" race that is so plentiful. Then you have to determine whether or not they'll be hitting corn or grazing in a pasture or eating worms and sprouts in a picked beanfield on rainy morning. What does this translate into? More than likely in an area like you live in there will nearly always be geese in the air doing something...somebody will always defy the rules and do something off the schedule. It's hard to ingnore these birds and they can tip you off to a loaf or roost but do yourself a favor and don't pay too much attention to them. You are looking for a pattern based on the numbers of individuals that adhere to it and the more the better...not some village idiot gander that defies the rules and flies into a picked beanfield with his family to eat frozen grasshoppers at 8am on a frosty morning.
Geese are very hard to understand because it takes lots of time to pattern them and most guys aren't willing to make the commitment which is usually work or gas money related. But, if you do start to pattern an area life can become much easier when it's time to exploit them.
