If you google chicken tractors, you'll come up with hundreds of ideas in addition to these. We're making: ours out of pcv pipe; I enlisted a friend to help us, turned out to be a big hassle; the pipe, which is special very heavy pipe, is still lighter than wood, but the connectors and stuff were more than I wanted to spend; we paid him about $200.00 to put it together for us, plus we bought wire ties, poultry netting and tarp. I'll post a picture when it is finally done
Maybe still cheaper than some coops, I guess.
