Before getting started, make sure you’re in synch with the local ordinances in your town. They do vary quite a bit.

Here are a couple of lists with the ordinances for Oregon and Washington cities as well as some national ones.  Because the interest in chicken raising is growing,  it is best to check with your own local laws.  If you find new information, feel free to let us know and we’ll update!  Thanks!

Urban Chicken Laws and Ordinances

It may be illegal for you to own chickens in your city, so call the local animal control office or your local municipality and ask what the laws are in your area. More and more ordinances are available online as well, so it’s worth doing a search. Since roosters are perceived as noisy, they usually tend to fall under your city’s noise/nuisance ordinances. While hens are normally very quiet, they may still be subject to nuisance ordinances. Check the city code before you get your birds and become attached to them! Some cities limit the number of chickens you can have on a given amount of land. In areas that were recently rural or have a strong farming culture, no law or license may be required to keep chickens. If chickens are illegal in your area all is not lost. Many people have managed to get pro-chicken ordinances passed by organizing and lobbying local government, such as Madison, WI, Portland, ME, and Ann Arbor MI.

What follows are laws from various US cities regarding the keeping of chickens.
