You got some good a advice from vtwaterfowler! It is a lot of work finding them in the early season since corn fields are not being harvested yet! New seedlings and fresh chopped fields are what you are looking for, alfalfa or soybean or pea fields are your best bet!
As for scouting I like to spot flocks in the air and follow them to thier feeding areas! Usually if you spot birds in the evening feeding in a field, usually they will head to the same field in the morning! However birds are starting to flock up now, the small family groups are begining to band together, and feeding in the same fields so you may have a small group of birds going to a certain field early in the morning and then have 3 or more small groups come in behind them until you have 50 or 60 birds there! But you may also get one flock of 50 birds and nothing after that! So you need to put the time in scouting and see what happens in the mornings! Sit on the fields you have seen birds and wait to pattern them , see how they come in, where they land, take note of wind direction, time, and count birds in each flock ! Forget roost hunting, that pushed them out of the roosting area, which means you have to locate them all over again! If you know they are roosting somewhere then you know how to track them in the mornings!!! You do not want to loose that edge!
Good luck and good hunting!
