A man was driving down a quiet country lane when out into the road strayed a rooster. Whack! The rooster disappeared under the car followed by a large cloud of feathers. Shaken, the man pulled over at the farmhouse, and rang the door bell. A farmer appeared. The man, somewhat nervously said, "I think I killed your rooster, please allow me to replace him". "Suit yourself," the farmer replied, "the hens are round the back."
