The easy words in large print catch Mr. Duck, who is in a perfect quack, as he rushes around the barnyard inviting his feathered friends over to his nest. They arrive in time to watch his first born emerge from the shell. This sequence of events is photographed from the first tap to the last lurch as the wet-feathered too-small-for-his-feet duckling emerges, to be joined by five brothers and sisters who show up in the book only when dry and fluffy. Large, clear photographs and simple explanatory text from the author of the well received Birds Will Come to You. Excellent material for the earliest forays into biology.
