This is a chicken tractor I built from the plans I got from Solarcabin. His website is http://www.simplesolarhomesteading.com/ I bought it from there. Very good read and a must have for anyone looking to be more self sufficient. Please like and SUBSCRIBE! Leave your comments below, I like interacting with you all. :) Note: I meant to say 2x4's for the run not plywood.
