The hens are the key to good egg production.What I want to know is how many people here are breeding for egg production, and what methods do you use to determine which pullets and cockerels to select as breeders.
If you keep only hens that have good egg production and the rooster/s are out of the most productive hen then your egg production will go up.
This holds true even in dairy animals, if you want to increase milk production in your offspring you breed only your most productive females to the male that came out of the most productive female.
