After seeing the different replies from folks in other states.... I think it's a "snow" thing. From my experience.... the turkey almost seem to panic and go into a survival mode once it snows. We also get huge flocks once the winter sets in. I've seen flocks of hundreds of birds hitting the same picked cornfield once the snow covers everything. We once had a flock of ove 200 birds that would come down into the coral evry evening we went to feed te cattle. It was awesome to see so many birds walking all around and through all the Black Angus cows to get at any spilled feed!
