Help! Does anyone use chicken runs for their outdoor enclosures?

Hi everyone,

I'm finally in a place where I can give my beloved three-toed box turtle an outdoor enclosure. I'm deeply cautious about protecting her from predators, so I was looking into chicken runs as a potential perimeter for her. Ideally a 6x6 or 8x8 run would be ideal. Has anyone else used chicken runs to develop their turtles enclosures and if so, any recommendations on particular products?

She's been my companion for 32 years and is at LEAST in her late forties- fifties. She's my little anchor in this crazy world and I want to do everything I can to continue giving her the best life humanly possible. Thanks all!
