I live in town and my birds are truly "backyard" chickens. Right now, my yard is fenced but only with 3 foot high chain link. Come spring, I'd love to be able to let the girls out of the run to pick through the grass and the garden whenever I'm outside. I'm certain that I wouldn't feel comfortable doing so with my current set-up. My neighbors on either side both have a couple large, rowdy doggies. If I kept their wings clipped and fenced the yard with 6 foot privacy fencing, do you think they'd stay put? I'm not sure if yard size or layout matters, so here's a pic of my backyard. For scale, the 6 garden beds are all 4' x 16', as is the Coop/Run which is represented by the yellow rectangle.
