"Cock O The Walk" joke

A farmer rears 25 young hens and one old cock.
As the old cock could no longer handle his job efficiently, the farmer buys one young cock from the market and puts it in the pen with the old cock and the hens…
Old Cock: Welcome to the farm.
We’ll work together towards productivity.
Young Cock: Whattya mean? As far as I know, you are old and should be retired.
Old Cock: Young boy, there are 25 hens here, can’t I help you with some?
Young Cock: No! Not even one, all of them will be mine.
Old Cock: In this case, I challenge you to a competition and, if I win, you let me have one hen. If I lose you have them all.
Young Cock: Okay. What kind of competition?
Old Cock: 50-yard dash. From here to that tree.
But due to my age, I hope you allow me to start off the first 10 yards.
Young Cock: No problem! We race tomorrow morning.
Confidently, the following morning, the Young Cock allows the Old Cock to start off and when the Old Cock crosses the 10-yard mark, the young cock chases him with all his might.
He was right behind the old cock in a matter of seconds and - BANG! Before he can overtake the old cock, he is shot dead by the farmer, who sighs and says,
“Damn. That’s the fifth gay chicken I bought this week. ”
