Simple Urban Back Yard Chicken Tractor Design

This has been the simplest, lightweight, light duty, chicken tractor design I've built. With some chicken wire, pvc pipe, 2x4s, wheels, and fasteners. It works well for domestic yards, if you don't have many day-time predators, and your able to keep an eye on the flock. It's not the most sturdy or rugged design which would be necessary to keep out more determined predators would easily be able to chew through the plastic wire or dig under the base of the frame. I've learned the hard way that with out extra predator proofing, under those conditions, you may be setting yourself up to fail and to loose your flock.
