The Chicken Farm

A man goes to the supply store and buys 300 chicks. He tells the owner, "I'm going to start a chicken farm!"

A couple of weeks later he returns and buys 300 more. The owner thinks it's weird but doesn't ask any questions.

Another couple of weeks later he returns to make the same purchase. At this point the owner is baffled and asks, "Why do you come back every couple of weeks and make the same purchase?"

The would-be farmer replies, "Well, I must be doin' somethin' wrong. I'm either planting them too deep or too close together."
