bock bock!!

There once was a farmer who ran a chicken ranch.One day the farmer decided to get a new rooster because his rooster was getting old.So the farmer went out and bought a new rooster and took it to the farm. Whereupon the new rooster was greeted by the old rooster, The old rooster said to the new rooster: Take a look around, there are 5000 chickens here for you at your beck and call. All you have to do is race me once around the barn.I am an old rooster so give me a twenty-five foot head start ok ?
The old rooster took off running and then the new one proceeded. just then the farmer stepped outside and shot the new rooster dead. and said d@mn it, that is the third queer rooster I have bought this week!
