I do not know of any laws or rules in your area. Look up the muni code for your city or county. I am heading up the fight to change the ordinances in my city. You will be surprised at how many people come out of the woodwork to support you and who want hens too! Do not be afraid. That is what keeps people silent. Start a group. Get the community involved. The people who don't want chickens are usually ignorant. I sure don't mean that disrespectfully. Ignorant is not knowing. They know fiction and myths. They say/think things like you have to have a rooster, they attract rodents, they attract bugs, they harbor and spread disease, they stink, they are loud. NONE of these things are true. you do NOT have to have a rooster, they eat bugs AND rodents if one happens in their path, and only roosters are loud! Get your hands on the book by Patricia called CITY CHICKS. It has a wealth of information on getting chickens legal and on micro flocks.
