The crow was confused about the number of eggs waiting for hatching.
When the chicks wriggled out of the shells, they all looked alike.
She fed them, enjoying their noisy tussle to get to the worms first.

As she was about to confront it, the chick sang, "Thank you, foster mother", and winged towards the melancholy song of a koel floating from far off.
