Outsiders will wonder how the chicken hatched. Insiders want to know what to pay attention to chickens. Here are the key points for hatching chicks. 1. Preheat eggs for incubation: Transfer the eggs kept in the air-conditioned egg bank to 22°C—25°C indoor preheat for 6—8 hours to remove water vapour on the eggs, and wait until the egg temperature reaches room temperature. Code plate hatched. 2, control the temperature: temperature is the primary condition for the development of chicken embryos, temperature control during incubation to be stable, to prevent the sudden change. The hatching period of the chicks was 21 days: 1 to 6 days incubation temperature of 38.5°C, 7 to 14 days of 38°C, 15 to 18 days of 37.8°C, and 19 to 21 days of 37.4°C. 3, control the humidity: control the humidity, the embryo can be heated evenly in the early stage, in the middle and late to help heat and clam shell hatching. Under normal circumstances, relative humidity: 1 - 7 days for 60% - 70%, 8 - 16 days for 50% - 55%, after 17 days for 65% - 70%. 4. Ventilation and ventilation: The embryonic development of chickens must continuously exchange gas with the outside world. Especially in the late post-incubation period, the embryos begin lung respiration, the oxygen demand increases, and the carbon dioxide emission increases. In this case, increase the ventilation and keep the air. fresh.
