In the tale, the little red hen finds a grain of wheat, and asks for help from the other farmyard animals to plant it. However, no animal is willing to help her. At each further stage (harvest, threshing, milling the wheat into flour, and baking the flour into bread), the hen again asks for help from the other animals, but again she gets no assistance.
Finally, the hen has completed her task, and asks who will help her eat the bread. This time, all the previous non-participants eagerly volunteer. However, she declines their help, stating that no one aided her in the preparation work, and eats it with her chicks, leaving none for anyone else.
If you have to do all of the work, at least you will have all of the rewards!
