Multistage incubation – selecting optimum settings
On the face of it, multistage incubation is an easy procedure. The setter is loaded with a new batch of eggs as the oldest batch in the setter reaches the point of needing to be transferred. A fully loaded machine contains eggs at all stages of incubation, and the average incubation age will be about 9 days. At this stage in a single-stage incubation programme, the eggs do not produce a lot of heat and their oxygen demand is limited.
