Check out Michael's sweet temporary chicken tractor!

"Here is another photo of this concept connecting three pins together each pen has 12 chickens one lays brown eggs, one lays green eggs, one lays blue eggs. These are temporary pens as they are not yet as they are not yet def egg producing age. I have connected  three panels with one rod.  I will break these down and produce individual tractors with enclosures and nesting boxes."
