The egg industry is one that has changed over the years from many smaller producers to one that is highly centralized and more specialized. In the early years of American agriculture, many farmers had chickens and collected eggs for their own use or for sale to friends, neighbors and the local grocer. Today, fewer farmers raise layers, and those farmers often specialize in egg production, maintaining large flocks of layers.
Prior to World War II, most egg production came from farm flocks of less than 400 hens. By the early 1960s, improved technology and the development of sophisticated mechanical equipment were responsible for a shift from small farm flocks to larger commercial operations. In the major egg-producing states, flocks of 100,000 laying hens are common, and some flocks number more than 1 million. Each of the 338 million laying birds in the United States in 2011 produced an average of 271 eggs a year. April 2012 ... Eggs
