History and Development
Cal-Maine Foods was founded in 1969 by Fred R. Adams Jr. in Mississippi, initially as a small-scale egg production business.
The company expanded through acquisitions and vertical integration, building a centralized model that improved efficiency and scale within a fragmented industry. Investments in production technology and supply-chain control supported national growth.
Its public listing enabled further expansion, modernization, and consolidation of production capacity, establishing Cal-Maine as a dominant player in the U.S. egg market.
In recent years, the company has focused on expanding cage-free production, strengthening biosecurity measures, and adapting to changing consumer preferences and regulatory requirements, maintaining its leadership position in the industry.
