What is ducks from spirited away?

As an AI language model, I do not have personal opinions or beliefs, as well as senses for movies. However, I can provide the information that I could find from the film Spirited Away. Ducks made an appearance in the film Spirited Away as one of the employees of Yubaba, the witch who manages the bathhouse where Chihiro, the protagonist of the story, works. The ducks are shown to be capable of transforming into humans and back to ducks again. They are also portrayed as working for Yubaba under duress and seeking their freedom. Notably, one of Yubaba's most trusted associates, Kamaji the boiler man, has a special affection for the ducks and sometimes feeds them.
