Mama and Papa Duck celebrate the hatching of their eggs, only to find that one is gone. Papa stays with their nine new ducklings, while Mama sets off to find the missing tenth. Along the way, she discovers four eggs hidden in nests, but instead of ducklings, they hatch a baby alligator, a python, a sea turtle, and a bald eagle. The author repeats a playful refrain that builds anticipation before every reveal: “Pretty soon she felt a wiggle, wiggle, wiggle. She heard a crack, crack, crack. She jumped up to look and…” Just as she’s about to give up, Mama Duck spots her errant egg and hatches duckling number 10, completing the happy family. This uncomplicated and clearly written read-aloud story manages to be educational without feeling didactic. Numbers up to 10 are introduced and reinforced, the concept of oviparous animals is explained, and an illustrated snail appears on most pages to provide an extra visual detail that young readers will enjoy spotting. This picture book succeeds because of its simplicity, clarity, and charm. Kids will delight in the surprise of unexpected animals hatching from the eggs; adults will appreciate the fun learning moments. Rogova’s full-page, endearing illustrations complement the narrative perfectly.
