according to the ordinance posted there is a maximum allowance of 12 hens so you seem to be ok on that...(don’t let chicken math take over). your coop looks great and your babies seem to be spoiled rotten!! you may want to get an idea how far your coop is away from other houses, roads etc as in that ordinance, there is a 30 ft minimum. in general the distances are from others houses etc and only relate to the coop itself. In general, if there is a complaint, the city would send a letter stating alleged violation and you have (x) amount of time to correct any violation and reispection etc before any fines are typically assessed. It is a very scary thing to have to deal with as our birds can be as much a pet as someone else’s cat or dog!!
