We are considering getting some chickens, about 3 bantams. My total yard is 1 1/2 acre with the back acre fenced in. I have an inground pool and covered patio. Before we jump into this I would like to know how much "mess" to be prepared for. I am planning on having a good size permanent coop but let them free range in my fenced backyard on pretty days. Will they work the entire yard or just stay in one area mostly? I don't want to fence in my pool area. I know they will poo but how much am I really looking at? I have two small dogs that "go" in this yard, and you hardly ever see it.
