Many buyers are unaware that the first digit printed on eggshells reveals how hens were raised. Codes 0, 1, 2, and 3 indicate different farming systems, from organic farming to caged systems. The packaging also provides information about origin, freshness, weight, and quality. The first digit is crucial for identifying the farming method, with code 0 representing organic eggs, code 1 for free-range, code 2 for barn-raised, and code 3 for caged hens. Additionally, the complete code on the eggshell includes the country of origin and production unit. Buyers should also check the quality class, weight categories, and freshness date before purchasing eggs.
