There are quite a few risks associated with owning chickens in an urban area. There would possibly be an outbreak in the form of Mice running rampant thru-out the streets due to more accessible food sources from chickens and their coops. I know as well as you that with more mice and other rodents comes more ways to spread infectious diseases among our families and pets. Not to mention other wild life coming into the city to feed on the hens and their eggs. No matter how tight you think you have the door on the coop secured a raccoon, cat or any other animal will be able to gain access. There is already a problem within the city with numerous stray cats running wild in the streets as well as dogs. The pound is always overloaded with animals that have been neglected or lost. Why place another burden on our tax dollars by adding another species of animal to the mix and force them to take control of livestock that got loose. The animal control office has enough to worry about with dogs terrorizing neighborhoods and stray cats all over, I'm sure the last thing they want is a call from a neighbor because a chicken is eating their garden they planted. Sure there is talk about instituting a permit to allow responsible people to own these urban chickens however not everyone abides by the law and buys the necessary licenses and or permits to own animals in the city. Criminals haven't cared in the past about obtaining the correct documents why would they start now. There are also numerous avian diseases that can be passed between the fowl and if not properly taken care of can become a real health hazard for people and especially children. The last point I want to bring up is the cost of the whole urban chicken coop. It has been documented that there would not be a significant return on an investment within the first 3 years or so. With the cost of said permits and building the appropriate coop to the cost of feed and nesting materials it would take an average of 3-4 years to see a return on the investment an urban chicken coop. Think about all of these facts and you decide on whether or not Warren would be able to accept a challenge such as urban chickens!
