Well, Kenny the rooster costs a lot of money, but the farmer decides he'd be worth it. So, he buys Kenny.

The farmer takes Kenny home and sets him down in the barnyard, first, giving the rooster a pep talk.

I want you to pace yourself now. You've got a lot of chickens to service here, and you cost me a lot of money. Consequently, I'll need you to do a good job. So, take your time and have some fun," the farmer said, with a chuckle.

Kenny seemed to understand, so the farmer pointed toward the Hen house and Kenny took off like a shot. WHAM!- Kenny nails every hen in the hen house- three or four times, and the farmer is really shocked. After that the farmer hears a commotion in the duck pen, sure enough, Kenny is in there.
Later, the farmer sees Kenny after a flock of geese, down by the lake. Once again - WHAM! He gets all the geese.

By sunset he sees Kenny out in the fields chasing quail and pheasants. The farmer is distraught and worried that his expensive rooster won't even last 24 hours. Sure enough, the farmer goes to bed and wakes up the next day, to find Kenny on his back, stone cold in the middle of the yard. vultures are circling overhead.

The farmer, saddened by the loss of such a colorful and expensive animal, shakes his head and says, "Oh, Kenny, I told you to pace yourself. I tried to get you to slow down, now look what you've done to yourself."
Kenny opens one eye, nods toward the vultures circling in the sky and says, "Shhh, they're getting closer".
