I’ve just completed a month-long expedition into Los Angeles County’s ordinances related to keeping fowl in an area zoned as residential, R1. Zoning, Animal Control, and Environmental Health were all contacted and it took a month to move the property owner to force his tenants to remove all the roosters and chickens they were keeping on the place.
Roosters crow all the time, day or night. Now, they do not because they have been removed. Hooray for the sounds of silence.
