I am working on plans to build a chicken tractor. It will be 10x20 feet, so I am planning on using PVC to keep the weight down as well as the cost. Been checking out what kind of wire to use and I came across this stuff: http://www.homedepot.com/h_d1/N-25e...yword=chicken+wire&storeId=10051#.UQneJR19LOs I like the look of it and the price is not that bad either. Narrow spacing on the bottom to deter the smaller wildlife (we have coons, possum, wild cats and such around here) and the larger spacing up top. I would run this along the bottom of the tractor and then use chicken wire for the top part to keep the hawks away. Anyone ever use this? Does is hold up well?
