When the farmer introduced the new rooster to all his chickens, the old rooster came up to the newcomer and arranged a meeting for later that night after the farmer went to bed.
"Listen," exclaimed the old rooster at the meeting that night, "that farmer thinks I'm too old to service all his chickens, but that's not true. I've still got a few good years left and I don't want to become the family's Sunday dinner prematurely. So let's make a deal!"
The deal that the old rooster had in mind was that the two roosters would get into a make-believe fight which would end up with the young rooster chasing the old-timer around the coop pretending not to be able to catch him. The noise of this make-believe altercation would bring out the farmer who would see the old rooster running faster than the new one and thus spare the old stud from the knife for a few years at least.
For doing this, the young rooster would get to fuck all the pretty chickens. The deal was made.
The next day the action started, with all the chickens squawking and the roosters cock-a-doodaling. The farmer came out and spied the new rooster chasing the old one. Picking up his rifle he shot the young rooster dead and exclaimed, "Goddamn! That is the third faggot rooster I've shot this week."
