This was a colorful little book for young children about eggs and the creatures that lay them. It poses a question at each egg illustration, and offers some possible solutions as to who laid it. Sometimes there are many suggestions, sometimes a few, sometimes only one! Children can have fun guessing who did what, and comparing the kinds of eggs to see if that can be used as a reliable clue. The animals include birds, turtles, dinosaurs, and even a mammal! This is a fun book for young children and I commend it.
