Semi-finished. With brown poultry it is possible to breed a variety that makes a visual distinction between a hen and a cock. A young female is brown and a young male white. This difference is essential at a hatchery for layer chickens, as males don’t lay eggs.The selection process is now less complicated and can be carried out by eye by non-specialized staff. Using a conveyor belt, 20,000 brown and white chicks can be separated every hour.The above-named difference is irrelevant for broilers as both sexes are bred for meat production.
