Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
This book is already a favorite of my 2 year old great-grandson. The illustrations are so cute and it is a good teaching tool to teach them to count from 1-10. This book is perfect after watching real chickens hatch out of eggs in their incubator. It would be great for kids who don't have chickens to watch hatch.
