The female and male chicks are raised independently until the age of 20-21 weeks, and during this period the birds are physiologically and sexually prepared for the production stage. During this period, the feed is selected to avoid unwanted weight gain within a controlled growth pattern. The length and intensity of lighting are also determined to control the growth process and to avoid the hormonal effect of intense lighting on the birds until the period of sexual maturity and the stage of photo propulsion.

Where males suitable for mating after selection are mixed with females ready for this process in the sex ratios recommended in the breed catalogue, allowing the production of fertilized eggs, which is the beginning of the (production stage).

The birds begin to produce fertilized eggs from the age of 25 weeks until the end of the flock. During this period, the weights of the birds, the weight of the egg, the amounts of feed, the physiological condition, and the sound physical specifications of both females and males must be controlled, as well as the maintenance of sex ratios during the various stages of life according to the recommendations of the catalog. The strain to ensure the best fertilization.

The eggs produced are collected 3 to 5 times a day and disinfected as quickly as possible to preserve the eggs from contamination. They are stored in the central farm refrigerators at the appropriate temperature and humidity for storage. The eggs are transported to the east coast hatchery by a fleet of cars equipped with the latest cooling systems and temperature tracking during the trip.
