Hatcher incubators are used during the last days of
the incubation process and this is when the actual hatching of the
chick will take place. The actual time when this takes place
depends on the bird type.
During the hatching phase of the incubation process, the eggs
are not turned as this would interfere with the hatching. Therefore the
hatcher incubator has no egg turning system, but temperature and humidity
levels still need to be monitored. During the hatching stage, the
humidity levels of incubator are increased to assist the chick
hatching through the hard egg shell.
