The longer I think about a food industry organized around an animal that cannot reproduce itself without technical assistance, the more I mistrust it. Poultry, a significant part of the modern diet, is emblematic of the whole dirty deal. Having no self-sustaining bloodlines to back up the industry is like having no gold standard to underpin paper currency. Maintaining a natural breeding poultry flock is a rebellion, at the most basic level, against the wholly artificial nature of how foods are produced.
