Legal in the S.F. Bay Area. In my city, for our lot size, we are allowed to have 2 hens without getting any permits. We rent, so we don't really want to go through the permit process with the neighbors. If we did, we could have up to 6 hens, I believe. No roosters allowed in our city.
We live against a hill, and there are tons of birds chirping all the time, owls hooting, and turkeys clucking on the hill. Every once in a while, the cows walk by and moo. I'm not worried about the noise of my chickens.
BAAAAD MOTHER CLUCKERS! I'm in Central Texas. We have 7 hens and got 2 letters from our city council saying chickens aren't allowed, we about to talk with the council. Funny thing is that if you didn't know better, you'd think our city is a neighborhood. Our city hall is a small one room building and a house. The real kicker is that the small towns on both sides of us allow chickens and then the larger cities, Austin and San Marcos, allow chickens.
Legal in semi-rural, unincorporated West Virginia. I still checked with my neighbors and they have no problem with roosters, a couple even said they like the sound!
Edmond, OK - Totally Illegal (and love it). 8 hens (2 are silkies) and 8 guinea fowl. Free range and all the neighbors love them. We actually didn't introduce the guineas - a neighbor did but they adopted our property, so we claim them!
Nobody has ever complained and our flock is well known as cars stop often to take pics of the guinea flock or the silkies.
I was an outlaw, but I got discovered, and my chickens certainly weren't something they were willing to ignore. Any tips on becoming an outlaw...? no privacy fences, the coop is going to have to be pretty incognito, and I live two doors down from my HOA leader.
