peccadillo - the result of a minor error by a south Texas chicken farmer who was experimenting with cross-breeding. Somehow a stray armadillo got into the equation, and the result, though flight-less (which helps with keeping them in) also turned out to be egg-less, and the meat tends to taste of formic acid. When laughed at by his neighbours the farmer replied "its only a peccadillo!" and the name has stuck.
The peccadillo is not to be confused with the armadicken. While also flightless, it does lay eggs, though they have a surprisingly tough shell.
