The chickens in a large hen house started to quarrel, wounded each other and many of them died every day. The upset farmer hurried to a consultant, and asked for a solution to his problem.

"Add baking-powder to the chickens' food," said the consultant, "it will calm them down."

After a week the farmer came back to the consultant and said: "My chickens continue to die. What shall I do?"

"Add strawberry juice to their drinking water, that will help for sure".

A week passed, and again the farmer came to the consultant: "My chickens are still quarrelling. Do you have some more advice?"

"I can give you more and more advice," answered the consultant. "The real question is whether you have more chickens."
