What are the types of incubators?

Setter

For the first 15 days of the eggs incubation period eggs must be placed in the setter, where they are turned every hour by the incubator. After the setting period eggs are physically moved to the hatcher, where they will hatch on the 17/18 day.

Hatcher

The hatcher is the part of the incubator where the eggs lay still for the last 3 days the incubation cycle. Generally the humidity and airflow is slightly higher at this part of the incubator due to the fact that eggs require a higher humidity towards the hatching phase. The hatcher creates a stable environment for the eggs to hatch in. No turning of the eggs happens during this phase. The chick inside the eggs aligns itself so that it can peck its way out of the shell.

Combination

A combo incubator is an incubator that combines both the setting and hatching phase. Design in which the setter and hatcher are combined into one device. Combo units work well when incubating and hatching smaller quantities of eggs. At a certain production level it becomes better to make use of separate setters and hatchers.
