The rooster really doesn't have anything to do with it. I have one particular hen who is the ringleader in taking small groups on exploration expeditions into the woods, across the power line easement and onto someone else's property. We've been working on a perimeter fence and she knows just where we left off, too! My rooster has been penned up for a few days due to a minor injury and she has disappeared three or four times with her small band of misfits anyway.
