We are happy with our chickens, about 8wks now, and they seem totally happy in their tractor. You know, the tractor that is supposed to have the benefit of working the soil because the chickens scratch and fertilize with their droppings. So what gives? I have never seen them scratch. Am I missing something? Lots of poop, though! As soon as I move the tractor my dog runs over to eat, not what I was hoping for either.
