The story

Three chicks (⺍) peeping over a nest (田) up a tree (木): the Shuowen describes 巣 as a bird's home in a tree. 巣 is a nest, 巣箱 is a birdhouse, and every March Japan's graduates 巣立つ, leave the nest for the wider world.

Used in 巣 (su, nest), 巣立つ (sudatsu, to leave the nest), and 卵巣 (ransou, ovary)
