I'm having trouble finding out what the ordinances are for my area - a lot of my neighbors have chickens, but I haven't heard any roosters. One of my babies is turning out to be a cockerel, and I'm afraid I may have to give him away, so I'm trying to find as much information as I can about what is allowed. I called animal control and they said that chickens are not "household pets" and are therefore not allowed in Residential zoned areas at all. I've also looked up ordinances online, but can't find anything specific. I have seen "crowing" listed as a noise nuisance, so that may be my answer right there. Does anyone from Contra Costa County know what the laws are? I live in an unincorporated area, zoned "R-7" for whatever that is worth.
