I live In Sandy UT and, while the gov't is at least looking at the chicken issue, they have gone overboard. To dictate the materials, the dimensions, the building, the cleaning, etc. is overkill. We are not 6th graders working on a science project (my apologies to 6th graders). And we are talking about less than 15 chickens. Most urban chicken people go above and beyond in making sure that they are not noticeable by smell, noise (roosters) or anything else that might get them in trouble. Technically, if I didn't live where I do, I wouldn't comply cause my coop is 7' tall and I used chickenwire stapled onto RR ties set at groundlevel. It is very clean, the 4 hens are relatively quiet and my neighbors are fine with it. Even in Sandy, I am not totally legal.
The neighbors 300' away didn't ask me if it was ok for their dogs to bark all nite or poop in my yard.
So I'm not asking permission.
