Fully automated, modular hatching system, with counter-flow based airflow for the accurate regulation of temperature, heating, cooling, humidity and ventilation, produces healthy, highly uniform day old chicks. Modular hatcher control prevents cross contamination from older to younger batches, because eggs of different ages need not be mixed. Securely placed and compartmentalized sensors in the central operating console allow for high pressure cleaning without risking damage. All surfaces, fixings and finishes are designed to resist the ingress of moisture and bacteria
