Our city chicken rules went into effect almost 3 years ago after people who wanted backyard chickens organized and lobbied effectively. Previously, city dwellers couldn't keep any chickens. Now we can have up to 6 hens (no roosters) after going thru a really exhausting and expensive permitting application process. This mornjng I was chatting with the very nice animal control officer who oversees chicken permits and complaints, and she told me that so far, in our city of around 100k, I'm only the 43rd person to get a chicken keeping permit, and she also said that there have been almost no problems with chicken keeping in the city since the ordinance went into effect: no smell, disease, increased predators, noise - none of the things she was concerned about when City Council approved the ordinance. So I asked her whether she thought we' d ever be able to keep more than 6 hens legally, and she said she just didn't think so because that's the # most cities have settled on with their backyard chicken rules. So I'm wondering, why 6? Why do most municipalities use that flock size in their rules? Also, does anyone know of any cities where citizens have successfully lobbied to raise the backyard flock size limit beyond 6?
