here is my chicken tractor. the bottom is 10X4 Pressure treated 2X4's held together with a L shaped metal brace. the ribs are 10' PVC schedule 40 pipes held on the outside of the frame with condiut clamps. the top mid rib is put on with outdoor rated zip ties. the chicken wire is green PVC coated wire held on with zip ties and stapled at the bottom. the tarps are camping tarps held on with bungee cords. This has taken me 2 days to do with no helpers. I probably could have gotten it finished in one day with help. I still have to fashion a door somehow. I think I'll use the PVC pipes bent into a U with elbow joints and a bottom piece. I can probably get the door to swing using zip ties but I'm not sure what kind of latch I can use. I have tomorrow off so I can probably get that finished then.
