Temperature control
Incubation period
The incubator temperature should be maintained at 37.5°C to 37.8°C (99.5°F to 100°F).
Hatching period
The hatcher temperature should be slightly lower, maintained at 37.2°C to 37.5°C (99°F to 99.5°F).
Stability
Temperature fluctuations should be controlled within ±0.1°C to avoid affecting embryonic development.
Humidity control
Incubation period
Relative humidity should be maintained at 50% to 55%.
Hatching period
Relative humidity should be increased to 65% to 70% to facilitate hatching of chicks.
Stability
Humidity fluctuations should be controlled within ±5% to ensure normal embryonic development.
Air quality requirements
Ventilation
The hatchery needs to have a good ventilation system to ensure air circulation and avoid carbon dioxide accumulation.
Oxygen concentration
The oxygen concentration should be maintained at 19.5% to 20.5%.
Carbon dioxide concentration
The carbon dioxide concentration should be less than 0.5% to avoid affecting embryonic development.
Air quality
Regularly monitor air quality to prevent the accumulation of harmful gases such as ammonia and hydrogen sulfide.
Other precautions
Cleaning and disinfection
The hatchery should be cleaned and disinfected regularly to prevent the growth of pathogenic microorganisms.
Equipment maintenance
Regularly check and maintain the hatching equipment to ensure its normal operation.
Record management
Detailed records of temperature, humidity, ventilation and other data are kept for easy traceability and analysis.
