What is the gestation period for geese eggs?

Birds, including geese, incubate their eggs, so there is no gestation period. For geese, this incubation period is 28 to 35 days. Geese lay 12 to 15 eggs per clutch. It can take up to three days for all the viable eggs to hatch.

Geese live in monogamous pairs and only change partners if one of them dies. The incubation of geese eggs is facilitated by the female, with the male remaining close by to assist in the protection of the eggs. In the northern hemisphere, the mating season for geese is from February to April. In the southern hemisphere, it runs from August to September.
