Adding the run to the tractor gives the chickens much more room … and much more visibility. Chickens seem to make people happy. They are like puppy dogs. Whenever people notice them they start to smile. Obviously they are popular with the kids in the neighborhood. I already got to meet some parents (dragged to my fence by their kids) whom I would have probably not talked to otherwise. I also had some neighbors who walked over to my place just so that the children of their visitors could look at the chickens.
