Check out this chicken tractor from Michael!

“Finally finished my chicken tractor. I made one out of PVC a couple of years ago but it didn't hold up. I learned the hard way that pvc is not UV resistant. I'm sure this one made of 3/4" EMT will last much longer. I'm so glad I discovered your products and your bending calculation tool to create the arches. I would have never been able to construct this otherwise!”
