American consumers buy regular eggs more than cage-free eggs by 40-to-1, according to checkout scanner data gathered from 34,000 stores by Information Resources Inc. Results were presented recently by the United Egg Producers, a national farmer cooperative and trade association for America’s egg farmers.

Eggs produced in traditional cage housing systems were the most popular eggs among supermarket shoppers, accounting for 92% of the 21 billion eggs bought at stores last year, according data. Cage-free eggs only account for 2% of all retail eggs bought, and organic/free-range eggs accounted for only 1%. Sales of all three types of eggs were relatively flat compared to the previous year.
