In poultry farming, the successful incubation and hatching of chicken eggs depend significantly on the proper management of the setter and hatcher. These two pieces of equipment are designed to provide controlled environmental conditions that simulate natural incubation and optimize the development and survival of embryos. The setter, also called the incubator, is used for the initial phase of incubation, while the hatcher is employed during the final days before the chicks emerge. Both require precise environmental and operational management to ensure high hatchability rates and healthy chicks. Temperature is one of the most critical requirements for both the setter and hatcher. In the setter, the temperature is typically maintained between 37.5°C and 38°C, while in the hatcher, it is slightly lower, around 37°C to 37.5°C. This specific temperature range ensures proper embryonic development, as deviations can result in slowed growth, deformities, or mortality. High temperatures can lead to dehydration of the embryo and abnormal development, while low temperatures can delay hatching or cause incomplete development. Consistency in temperature is essential, and both machines are usually equipped with thermostatic controls to maintain a stable environment. Humidity is
