Sorry if this is dumb question but I am new to this. I am raising my first flock of hens (no rooster). I have gradually been letting them free roam for a few hours every night. They stick near the coop and its enclosure and run into it any time they sense danger (like my daughter running over to hang out with them). I would like to get to the point when I let them roam all day. I have over 5 acres with the house and several other building so they have plenty of areas to duck for cover if needed. My concern is my property is surrounded by hundreds of acres of cornfield. Is there any chance of a bird wandering in there and getting lost? I'd hate for one of them to sprint into it for cover and not be able to find her way out. Would she call to the others for direction? Thanks in advance.
