I will correct the errors and add words to your translated story to try to make it read better in English. Please note the changes:
The Clever Hen
A hen had gotten a single grain of wheat and then wanted to eat it, but she stopped and she thought carefully and said, "I will sow this one so I will have a lot of wheat."
After she planted it and watered it well, that one grain of wheat grew into seven heads of wheat. The hen collected all the wheat, cleaned it, ground it into flour, kneaded it into dough, and then baked it into bread.
She then collected her chicks and fed them some bread. She said to them, "All this nice bread has come to us from just one grain of wheat; so my chicks, you have to plant and wait to get the best results. This is because it is blessed to have food to eat; but, with patience, you shall enjoy the greater reward!
I know I took some liberty with your story, but I hope I captured the feeling and intent of the original. I like stories or fables that teach morals. I think most all languages have these kinds of stories. Do any of you other students have a short fable to translate into English that you would like to share?
