Yes I know of the policies on it and while we are very dense it doesn't make it impossible for people to have their own chicken coop if they have a backyard, especially areas outside of downtown. And I could be mistaken but I recall reading that if a person has written consent from their neighbors approving the coop if the 25 ft limit cannot be met. The link you posted dates the ordinance is dated from 1978, I recall the city council updated or were looking into updating the ordinance to promote more urban farms within JC.
