FIELD: animal husbandry.

SUBSTANCE: group of inventions relates to the field of animal husbandry, in particular to a system and a method for the stimulation of the hatching of female chicks from chicken eggs. The method includes incubation of multiple fertilized eggs to stimulate the hatching of fertilized chicken eggs, transmission of a sound wave with a given frequency to fertilized eggs during incubation and before hatching, wherein the specified given frequency varies from 100 Hz to 2000 Hz. The system is characterized by that it contains an incubator for incubation of fertilized chicken eggs, a sound wave transmitter made with the possibility of transmission of a variable frequency varying from 100 Hz to 2000 Hz during incubation to stimulate the hatching of female chicks relatively to male chicks from the fertilized egg, and a controller made with the possibility of control of the transmitter to transmit a sound wave with a variable frequency ranging from 100 Hz to 2000 Hz.

EFFECT: use of the group of inventions will stimulate the hatching of female chicks relatively to male chicks from fertilized eggs.
