We built the tractor last spring. I used it for a batch of Welsummer chicks for several months. My neighbor borrowed it and used with her larger chicks for a couple of months. I have occasionally used it for isolating an aggravating rooster who needed some time-out. It's still in great shape. I moved it daily with my chicks--just lifted one end and walked to a new patch of lawn. Two people can attach the chicken wire with no problems.
