be carefull for open pens for stray animals like cats believe I learn my lessonI would like to try clipping the wings so I wouldn't need a covered run,
but that might be time consuming.
This guy has been free ranging for most of the daylight hours then I herd him back in the pen with the turkeys and guineas,
but he seems to resist much more
That will not keep a hawk or an owl out.And don't forget those pesky raccoons that come out at night and your gaurd animals are sleeping.Raise them right with a covered pen and you will not lose them to any predator if your pen is done right.I have a perimeter fence around my property and many watch/guard animals to keep predators away, this would be a tighter fence inside probably near the center.
Or maybe a long narrow run with deer netting on top
