If your coop smells like something died you may want to review coop maintenance, as normally a properly cared for coop has little smell, and should not be foul.
No matter what you wish to cite, be it animals, gardens,or motorcycles, there will be those who do not do everything they could to care for their possessions properly. Those people should certainly be corrected. Even without specific regulations for chickens, animal control agencies are responsible for the welfare of all animals, and can act if neglect is suspected. Barring everyone from having chickens because you don't think some will do it right seems quite draconian, and smacks of government intrusion.
