The invention relates to a subpopulation of the white Rhode-Island breed, a homozygote for the silver gene, intended to producing the simple hybrid female (5C x 5D)- necessary for obtaining, by its crossing with the simple hybrid male (5A x 3B)- belonging to the red Rhode-Island breed, the ROSO SL-2000 hybrid hens employed in the production of consumption eggs with pigmented shell, designed for the population. The heterosomal silver and golden genes have a role in transmitting the feathering colour to the one-day-old hybrid chickens and allow to distinguish the hybrid young cocks from the hybrid young hens. The line productive features are: 304 eggs per foddered female in a productive cycle, with an average egg weight of 58.7 g and 61.5 g at the ages of 26 and 34 weeks, 1960 g the average female weight and 2740 g the average male weight at the age of 34 weeks; the hens lay the first egg at the age of 154 days; 96% the youngster viability and 95% the adult viability, 90.9% average fertility and 81.3% egg hatchability. The poultry in this line are calm and resistant to diseases.
