"Where Do They Go?" is a poem for children by L. Frank Baum. It is one of the two poems that was printed in both By the Candelabra's Glare (1898) and Father Goose (1899) — the other being "Who's Afraid."
Father Goose prints only the first stanza of the poem, as illustrated by W. W. Denslow — "Where do the chickens go at night — / Heigh-ho! where do they go?" The earlier text prints three additional stanzas, about a kitten, "our little dog," and "our baby."
The poem is also included in The Songs of Father Goose, as "Where Do the Chicks Go at Night?"
