Dead rooster

A man was driving down a quiet country lane when out into the road strayed a rooster.

Whack!

The rooster disappeared under the car in a cloud of feathers.

Shaken, the man pulled over at the farmhouse and rang the doorbell.

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

Spoiler:

"the hens are round the back".
