FIELD: poultry farming.
SUBSTANCE: invention relates to the field of poultry farming, in particular to the breeding of poultry. The method for early assessment of egg productivity of laying hens includes keeping birds in individual cages from the age of 120 days and conducting daily observations of their egg production. Starting from the age of 150 days, within 30 days, the number of eggs per cycle and the number of intervals between egg-laying cycles are taken into account. The bird, in which for the specified period the number of eggs per cycle is 14 or more, and the intervals are less than 3 days, are classified as laying hens with high egg productivity, the rest of the bird is classified as laying hens with medium and low productivity.
EFFECT: early assessment of egg productivity.
