I just finished building our new chicken tractor. I combined ideas from several designs that I found on the Internet. The finished tractor is 8.5′ by 11.5′. The hoop is constructed out of two cattle panels. It is light enough for one person to move which is a big plus in my book. A chicken tractor of this size will easily accommodate 50 broilers. We have two batches of pastured poultry left to butcher this year; one towards the end of October and the last batch in the middle of November. Hopefully we will have a couple of warm days left that we can butcher on.
