Gotta love the man for it, but... He built it for me about 10 years ago, I just replaced the chicken wire on the sides a few days ago (he had the 2" mesh on it, rusting and not good for chicks). The only 'problem' is, he got some plans and decided to make ours 'stronger' than the one in the plans. For example, if the plan called for 1x4 wood, he used 2x4's. So I have this very nice chicken tractor, which has held up very well over the years. But I don't think 'chicken tractor' means that you NEED a tractor to move it! On the plus side, he built me a very nice hen house, insulated it, and painted the inside white. It may show all of the dirt, but when you turn the lights on in there it's nice and bright!
