A BBC science article headline provided a brief titter today :

Scientists solve half-cock chicken mystery

The less smutty sounding real story being rather interesting none-the-less :

About one in every 10,000 chickens is gynandromorphous, to use the technical term.

In medieval times, they might have been burned at the stake, as witches’ familiars.

They did seem to do rather a lot of burning in the middle ages.

Witch!
