I have a small flock of 7 (6 hens and a roo). They have a covered run that is 10x20 but they LOVE to come out and peck around the yard...which isn't a big deal EXCEPT we have hawks out the ying yang where I live. Free rangers- how do you do it with out driving yourself nuts thinking about something coming along and killing your chickens? I lost two hens last Summer to raccoons, and since then I am terrified to let them just wander around on their own. I mean, surely 100 years ago farmers didn't chicken-sit their flock outside...they just let them out and that was that. Right?
