Gwen the hen has laid her eggs, but just how many is anyone's guess. For now, she's quite content to sit and wait for them to hatch. Red Rooster, however, is too excited to wait. As soon as one egg hatches, he struts over to Worm World and buys one worm for his one new baby chick. Alas, Red returns to find that not one new baby chick, but two baby chicks have now hatched, requiring a return trip to Worm World. The hijinks continue back and forth until ten eggs have hatched, Red Rooster is very tired, and young readers have learned a thing or two about counting to ten.
