FIELD: agriculture.;SUBSTANCE: method to increase synchronizing the chicks hatching involves incubating hens' eggs. The incubation regime is that from the 1st to 4th days of incubation the incubator temperature is increased to 38.5°C, and from the 5th to 17th days of incubation the incubation temperature is 37.5-37.6°C. Since the 18th day till hatching the temperature in the incubator is 36.5°C, and in the same period the carbon dioxide concentration in the incubator is raised to 0.5-1.0%.;EFFECT: invention allows to increase the chicks uniformity by synchronizing their hatching in time.;1 ex, 1 dwg
