I live in the city and have a relatively small fenced in backyard. I do have two side yards and of course a front yard. I would like to purchase a portable pasture pen for my five chickens. Would like to use them for natural fertilization, and pest control not to mention putting them in the garden in the fall. I love my husband but he nor I are very handy. Has anyone purchased a quality portable pen at least 6 feet long? Need to let the backyard rest and when they no longer are laying they will still be usefull.
