Blackbird and the Blue Balloon

Why a blue balloon? Well everything has a beginning, and a blue balloon drifting above us when walking our little dog in our local park one day, set me thinking. My story begins on a farm. Little animals are going about their normal lives, when a blue balloon drifts overhead. They wonder where it has come from and where it is going. Pigeon flies to investigate and Blackbird follows. Bluebell would like to fly but she is only a little field mouse. Blackbird wants to help and flies over to a nearby Bird-garden to seek advice from his friends.
