FIELD: agriculture.
SUBSTANCE: method of early forecasting of egg productivity of chickens includes early selection of chickens by egg productivity. At the 10-th day of life the assessment of constitutional attribute, namely the length of tibiotarsus, is performed and a young growth with the length above 28 mm is selected for the further selection for the herd of chickens with high egg-laying capacity.
EFFECT: offered invention allows to form high productive herd of egg production chickens.
