Hard to say on that one. Four years ago on the NC opener I had 5 hens and 2 jakes fly down on an oak flat about 75 yds from me. They fed and milled around for a few minutes and then, out of nowhere, one hen pitched straight back up into a big oak. All the others followed suite and they just sat up there, preening and fluffing their duff for about an hour. Looked like a bunch of high school kids lined up in front of the bathroom mirror.....it happens.....
