I am intrigued by the chicken tractor being sold by Randall Burkey. It is called the "Egg Cart'n" and supposedly holds 12 standard hens. Personally, I think it looks a little small for 12 hens, but it appears to be very sturdy. And, unfortunately, it is anything but cheap, but it looks to be better than the product sold by Omlet. I am curious whether anyone on this forum has seen or used this product.
