I am a city council member in a small town in South Dakota. I am sympathetic to the idea of permitting folks to keep a few chickens as people did in my town years ago. Since the people on this site are far more into this, and knowledgable than me, I am hopeful I can get a little help in moving my community forward (or backward seventy years, depending upon your perspective). What are the reasonable restrictions that should be placed on citizens, number of birds, roosters, sanitation, acreage, etc.? What are the responses to the arguments people make to having chickens in a community, sanitation, noise, proliferation of other farm animals? Thank you in advance.
