It's really a shame that so many cities ban chickens altogether. It's just the result of ignorance and prejudice.
Fortunately, I have a couple acres outside Alamogordo, NM limits and desert space around me. After my husband died 4 years ago, I embraced chicken addiction in earnest, and now have about 60 breeds of poultry plus peafowl plus dogs and cats and a couple EMUs. My critters have consumed about 3 tons of feed monthly at times, most of it bird food.
Recently a young woman who is blind, her husband, and a friend who live a few miles from here, in town, had nasty trouble from a neighbor over their 6 pet chickens which actually spent much of their time in the house with them, especially overnight. I give them credit that they looked into the possibility of changing the law here and kept those 5 hens and 1 rooster at home as long as they could. I'd heard that it's very difficult to get the law changed.
After a judge ordered them to remove their birds and they had a deadline, they brought them out to my place. They were afraid they'd be confiscated and destroyed. They were heartbroken. But they built a nice secure pen with 2 levels of enclosed area; and they love those birds more than most people love their dogs and cats, I'd say. They are here every day, sometimes 2 or 3 times, enjoying their beloved pets. These chickens have a thick bed of straw throughout their pen plus good alfalfa hay, regular feeds, and still get their daily cheese as they always did, and plenty of other goodies.
The nasty neighbor kept up the harrassment and even got the animal control officer to come to check on them the day they had to be removed. Then he gloated about his success. What a miserable person.
These people would move out of the city to keep their chickens and have been looking for a place. Meanwhile, they come often.
More power to anyone who can and will work to change these stupid laws. Now is probably the time, considering the economy and changing priorities. My contribution is letting visitors enjoy the multitude and variety of birds here, and selling some when I can.
For myself, I quit eating chicken some time ago.
