why did the birds decide to send a messenger to men
Long, long ago, as the birds flew over the world, they saw that men had a beautiful thing.It was a bright, burning thing.Men cooked their food and kept warm with it.The birds thought life would be better if they too could have this thing.So they decided to send a messenger to humans to ask for a little piece of it.They thought that Chicken was a good one to send because he was a good talker.So Chicken went.He flew far over the forest until he came to a small town.He saw the burning thing.He learned that it was called "Fire".But he did not ask for a piece of it.There was so much food lying around men's houses that he started eating and forgot what he had come for.Men liked Chicken because he crowed very early in the morning and woke them up.They let him run in and run out of their houses.They threw him food.So Chicken stayed with humans.He never went back to the birds.He even forgot how to fly.
