It's spring. One day, Mother Duck finds four eggs at her home. Three are small and one is big. She sits on the eggs. Three small eggs open. The ducklings are small and yellow. The big egg opens later. It's big and grey. It's ugly. Mother Duck doesn't like the ugly duckling. He is sad and swims away. In winter, it's cold. He has no home. It's spring again. The ugly duckling becomes a beautiful swan.
