This type of selective breeding works like every other; you simply only breed subjects which display the certain characteristics you want.
Basically, selective breeding for high egg production works like this - You watch your hens, and see which of them are the most prolific layers. Then, you breed them to different roosters, hatching out those babies. Recording which parents they have, wait until the F1 hens start laying, and see which bloodlines produce offspring that lay more eggs.
All in all - its just a passing of genes and ect.
