Wanted to show you all my chicken tractors! The R one we bought on Craigslist; the L one I built from scrap lumber and some chicken wire. They each hold 6 chickens, but we're housing 5 in each. Seems plenty full. We move them around the yard, giving them new grass at least once per day. They pretty much decimate the grass but I think it'll come back with all the fertilizing going on.
