I am completely in support of this cause. Chickens can certainly be raised in an unobtrusive manner, clean, and with many benefits. Not only are they good, interesting, beautiful pets, but they also provide a very important source of local food, both eggs and meat, both of which are far superior to store products. It is far healthier to get our food locally, whenever possible. They even help improve the soil's fertility, by composting their bedding/chips and enriching the soil - a wonderful free benefit that also helps raise better and healthier garden crops. Healthier people require less medical procedures, thus saving money.
Not being able to raise chickens would be like not being able to grow one's own vegetables!
