About the Industry
Prior to World War II, most egg production came from farm flocks of less than 400 hens. By the early 1960's, 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 not unusual and some flocks number more than 1 million. Each of the 235 million laying birds in the U.S. produces from 250 to 300 eggs a year.
