This morning when I was letting mine out, I heard a Bantam rooster farther away than the neighbors that I know have chickens, so that brings our neighborhood total to 6 roosters, 1 for me, 1 for that far away Bantam I heard, and 4 for the people that live behind me. And we're in a township that allows them for now, in a pretty tight 1950's style neighborhood. It's small though, with a golfcourse across the road, and two parks, and all the chickens seem to be on the last 2 roads near the "buffer" properties lacking houses. So there aren't that many people to complain, and with the barking dogs... who would, unless they want the cops out for barking dogs? We seem to have a "I won't say anything about your critters if you don't say anything about mine" thing going on.
It totally helps to talk with your neighbors, I think that's why we're still allowed to have roosters. There's horses down the road too, they'd have to totally change the zoning, and the guy that owns the horse farm just built the $700,000 facility, and is influential in the township, so I think we're pretty dang safe unless they opt for a rooster ban. But, no one has said anything, thus far.
They only complaint I've ever had was when my previous chickens free ranged from the front yard and went to visit the neighbors, scratching mulch from under their bushes onto their driveway. Fixed that this time around by building a run in the back yard, and they free range in the backyard only.
Roosters in a no-rooster zone though... try it till someone says otherwise! You can always claim ignorance to the ordinance, I haven't heard of anyone paying a fine the first time, only after several visits when they don't comply with the original warning.
