Here is a little info I got regarding chickens in Sierra Vista. I searched EVERYWHERE! I poured through ordinances and found nothing. Finally I called the city directly and here is what they said.
First they told be no, but the lady's tune changed a bit when I asked her for the ordinance number that states they aren't allowed. The city does not have an ordinance that addresses chickens anywhere. In the end the conversation basically concluded with, "If they are reported as a nuisance, you will be asked to remove them." I dont think you can be legally fined or anything though since there isn't anything documented. There are however still neighborhood restrictions in the.....what do they call it? CCRs?
Another bit of info I found was an article regarding a city council meeting about the keeping of poultry back in 2011. The article isn't clear about the outcome of this meeting, but in my call the woman told me that no ordinance one way or the other was created because it is such a controversial topic. This upset me because in my eyes, doing nothing is practically saying no.
So anyway, if anyone has more information about this topic, or has the know how to actually get the city to get with the program, that would be great. In the meantime I plan to check with my neighbors and get a few anyway. City can't take away what they dont know is there.
