A story that clearly illustrates the saying. Do not count your chickens before they are hatched

I probably know that chickens come from eggs. A female chicken or hen lays eggs and then they hatch into chicks. Well, not all of them. Some eggs do not have a baby bird.

So, at our farm, a hen produces 15 eggs. If the farmer counts the eggs, she might expect to have 15 chicks once the eggs are hatched. But then five of those eggs do not hatch. Her expectations were not met, so she feels disappointed. She tells her friend how sad she feels. The friend may say to her, “Well, don’t count your chicken before they hatch.

Another way of saying this proverb is: “Don’t count your chickens until they are hatched.”

Explanation:

in ray bradbury's short story "a sound of thunder", mr. eckels's fearfulness leads to drastic consequences for the rest of the world.

in the story, mr. eckels, who is a hunter, hires a time travel company to travel to the age of dinosaurs. although he is excited for the hunting expedition at the beginning, when they reach there and mr. eckels sees the tyrannosaurus, he feels frightened. as he is afraid of the tyrannosaurus, he steps off the path although he has been warned not to do it. by stepping off the path, the entire course of the future is affected: mr. eckart alters the future by stepping on a butterfly, which causes a new man to be elected president in the future. in that way, it is mr. eckart's fearfulness what triggers 'the butterfly effect' and what leads to drastic consequences for the rest of the world.
