In my experience, most towns allow for three chickens to be kept, while roosters are usually prohibited. I live in a pretty upscale neighborhood, and I have a neighbor who lives in a $400,000 house who keeps his quota, they don't bother me. He seems to do it as a hobby, the chickens have stunning colors. They do unfortunately, get loose at times, and one of these days my German Shepard is going to eat one of the little b*stards.
