Now that I think of it, we do have a lot of industrial chicken farms in Northeast Texas. Ever driven close to one? The smell will put you off eating for a few hours. Not something to be proud of.
Then again, cattle "feed lots" are really nasty, too. Lots of those in West Texas. They are the main reason I spend extra money for grass fed and finished beef. All cattle are grass fed, until the last months of their lives. Many are sent to "feed lots" where they live in mud and their own feces, while gorging themselves with feed corn to fatten them up for sale. Those cattle are pumped full of antibiotics -- because they are living in mud and their own feces.
Sorry if this bothers anyone, but it is something we all need to know -- at least in countries like the US where this practice is allowed (and financially rewarded). Feed lots are like sweatshops in manufacturing. Whether it is meat or a pair of shoes, we try not to think about it, as long as we get them cheap.
