Here in NJ the ordinance about chickens was just ammended two years ago. Property's under 9,500 square feet are allowed 3 hens. Roosters are not allowed. I do not understand many of the towns ordinances pertaining to "livestock" My 140 pound bull mastiff is a bigger nusance to my neighbors than chickens, goats or even a pig. My town was concerned about attracting predators, fox, coyote and bear. To be honest 11 years ago I would see alot of critters hanging around. My dog is about to turn 10 and my property no longer has these critters. She has chased bear, and fox. I don't even have squirrels visit my yard. Every night I do hear the neighborhood raccoon knocking over every garbage pail on the street, except mine. I would say if left to assume, assume in your own favor. I would not draw attention to myself , so rule out roosters. if it comes up about you violating a town ordinance, I would do your research and visit a town meeting and request the ordinance be changed. It can be done, just takes time. And research to enlighten officials about what chickens really are.
