This entire article is fascinating on many levels, so I recommend reading the entire thing.
But, this passage just blew my mind ....
In 1969, according to a study by a group of CDC researchers led by Jeremy Sobel, the nation’s eggs were produced by 470,832 layer-hen farms with an average of 632 hens per farm. By 1992, the number of farms had dropped by 85 percent, while the average number of hens per farm increased by 470 percent, to nearly 3,000 hens per flock. Today, according to the American Egg Board, approximately sixty-three companies—each with flocks of one million hens or more—produce roughly 86 percent of the nation’s eggs. Seventeen of these companies, says the American Egg Board, have flocks of five million hens or more.

That is a mind-boggling transformation, and nearly the same thing has happened to every aspect of our entire food chain.
