[23] [25] Young Canada jays leave the nest between 22 and 24 days after hatching, after which the third bird begins to participate in foraging and feeding. [23] Natal dispersal distance for the Canada jay is a median of 0.0 km for males, 2.8 km (1.7 mi) for females, and a maximum distance of 11.3 km (7.0 mi) for males and females.

In the gray jay, non-breeders allofeed the young after fledging. [5] Not all species of jays allofeed their young, such as the Siberian jay (P. infaustus). [5] In Siberian jays, non-breeders do not allofeed the chicks of a breeding pair. [5] It is predicted that Siberian jays do not display allofeeding because the cost of predation is too high. [5]
