21 days is the usual gestation period for chickens. As a breeder however, I have found that sometimes the bantam breeds will hatch as soon as day 18, whereas the larger breeds will hatch around 21 days. They can also hatch earlier than usual if the temperature is too high in the incubator.Source(s): Chicken breeder for 7 years
