Before World War II most U.S. egg production came from farms with flocks of less than 400 hens. But as with farming, improved technology and consolidation has pushed small, usually family operations aside and large factory-like operations have become the norm. More than 80 percent of U.S. egg production comes from 63 egg-producing companies with flocks of at least 1 million hens. Seventeen of those companies actually have flocks of more than 5 million.
You’ll be forgiven if you believed the hardest part of shipping eggs was damaging the shells. Because of the ingenious design of the egg carton, differing takes on that design and various cushioning material, eggs are no more susceptible to damage in transit than other perishables.
