some 10 years ago a friend of mine (who lives pretty much in uptown Charlotte!) also had oriental neighbors with chickens...oh well, small world, could it be the same family
chicken is considered a farm animal, and if the zoning is not farm that means they are violating the ordinance. Sooner or later they got a yellow letter from the city.
but my friend also had 2 dogs...so I don't know if it was the city or the dogs (who did take a bite)...but they got rid of them
