The PVC bends naturally. I used 10 foot pieces of 1/2" PVC, others have said 3/4 inch. I did talk to a plumber in Lowes when I was buying it and he said to soften it up to bend even more you can leave it in the sun or heat it with a blow dryer. I used 1" chicken wire and then a second layer of 1'x1' plastic deer fencing that I found at Lowes. I have used the plastic fencing before and it is strong. I extended the chicken wire out 12" from the base of the run as a deterrent from anything digging to get in.The run I made was 5'8" x 15 feet. I am in the process of building the coop. It will be detachable and go at the back end. Right now I have a tarp over the back part with a roost underneath for the kids. It is still a work in progress but for now it works and it cost me less than $75 to make.Brookhaven i have seen those pens with PVC.. on here How do bend the pvc?What diameter do you use.? Do you use hard ware clothy and is there a coop or just the run?
