FIELD: animal farming.
SUBSTANCE: method involves measuring longitudinal size l and transverse size b of egg; providing automatic sorting out of eggs on the basis of l/b ratio by sex features, taking into account that ratio of l/b =1.4-1.5 is applicable to future cocks and ratio of l/b=1.2-1.3 is applicable to future hens.
EFFECT: increased efficiency in sorting out of eggs.
