This is a wonderful little book.  It could be an allegory for adoption, but in actually is an allegory for egg donation like what happened to the author.  The author wrote this as a way to help her child see that she is precious even though mom had to have some help getting a chick.  Most stories like this focus on the child understanding they are wanted and loved, but this one looks at the parents struggles and how sometimes they need a little help.  This was a wonderful story; it has a cadence and rhymes well.  The illustrations are eye catching and capture the heart of the story.  Overall, this is an excellent addition to any library.
