Tillie Lays an Egg by Terry Golson is too cute! It is also the new favorite of my two year old who carries it around the house talking about Tillie (or Towie to her). She even took it to daycare to share, and since this is a library copy I have one in my cart on Amazon right now. Tillie, the hen lives with six other hens. While the other hens take turns in their nesting beds, Tillie likes to explore and ends up in various rooms of the house where she lays eggs. Each page has young readers looking for the egg that Tillie laid. While I didn't notice right away, my observant children noted that the props in the background had a chicken/hen theme. I loved that this book features photographs with such bright and clear colors.
