The Pelican's newborn Chicks make a brief appearance near the end of The Female's World. The one in the middle eats Nefaria.
The Female's World:
During May and the circus clowns' encounter with the mother pelican, the chicks are seen having not yet hatched from their eggs. By the end of the film, they had hatched and were seen preparing to eat Nefaria, who was being held by their mother after Nefaria mistook her for a fake bird, thus ending her reign of terror and insult on the person colony.
The chicks are all portrayed as having downed bodies and open eyes (much like the offspring of chickens and ducks), while in real life, chicks born to passerine birds are often naked and blind at birth.
