The gestation period of a goose is called the incubation period. After the incubation period, if the egg is fertilized, a chick will hatch.
No, gestation is development in the uterus. Eggs have an incubation period.

The gestation period for parrots is 21 - 28 days.
Probably because they have no gestation period. Although their eggs have an incubation period.
Geese have a gestation period of 28-35 days. They have a lifespan of 10-24 years.
The gestation period is 19-21 days from the time the tiels start sitting on the eggs.
a fish lays eggs so it doesn't have a gestation period
The gestation of sparrow eggs is 10-15 days and incubation is shared between the parents.
