The incubation period, in which the female incubates while the male remains nearby, lasts for 24–32 days after laying. Canada geese can respond to external climatic factors by adjusting their laying date to spring maximum temperatures, which may benefit their nesting success. [40]

Three days before the eggs are scheduled to hatch, they are moved into a hatcher unit, where they are no longer turned so the embryos have time to get properly oriented for their exit from the shell, and the temperature and humidity are optimum for hatching.
