I share one border of my lot with some Romanian immigrants who have a ton of chickens. There is no fowl smell, they keep their run super tidy, and their chickens are kept as immaculate as any I've ever seen at the fair. Oh, and, they aren't housed in a "chicken coupe".
The way I look at it, Big Mo has no excuse. If the Romanians who moved here from a third world dumpster can figure out that a certain level of cleanliness needs to be maintained if they want to keep their pet chickens, then why can't she?
