How can selective breeding increase the production of eggs?

Selective breeding can increase egg production by choosing parent birds with desirable traits, such as high egg yield and improved fertility. By mating individuals that consistently produce more eggs, breeders can enhance these traits in future generations. This process can also involve selecting for traits like better feed efficiency and disease resistance, which can indirectly improve overall reproductive performance. Over time, this targeted approach results in a flock that lays more eggs than the average population.
