Genetic pattern of the breed of hen
Maximum production of top-quality eggs starts with a closely controlled breeding program emphasizing favorable genetic factors. Sex-Links are the most productive brown egg layers be cause they are a mix of two high productive breeds. If you were to breed a very low productive chicken with a high productive chicken, the next generation would not be nearly as productive as their high productive parent. But if you were to cross a high productive breed with another high productive breed the next generation would be just as productive or more productive than there parents

Definitely the breed and health of the chicken. Breeds such as leghorns have been developed to become prolific egg layers, for commercial use (the eggs you see in the store were probably laid by a leghorn!), whereas decorative breeds such as the polish or sumatras do not produce as many (there are exceptions though!)
