What is the gestation period for blue jays and how long before the new chicks leave the nest?

The gestation period for blue jays is not applicable since they are birds that lay eggs; instead, the incubation period lasts about 16 to 18 days after the eggs are laid. Once the chicks hatch, they typically remain in the nest for another 18 to 21 days before fledging, or leaving the nest. During this time, the parents continue to feed and care for the chicks until they are ready to fly and forage independently.
