Here is a better picture

There is much more room than the first pictures led me to believe.
I like using these hog panels for making arches for trellises and greenhouses. This winter I kept my chickens in a hog panel greenhouse. I just attached my small chicken tractor.
Awesome, we’ll see how long the panels last, slight rust already. Very humid down in Houston :)
I would guess a very long time. It is likely just surface rust. I have seen old fences made with these, they were covered in rust, but seemed fine. Posts will need replaced before the fencing.
