... evolutionary theory demands that somewhere over the last five or ten thousand years out of all the chickens which have ever gotten loose, some should have regained whatever is lacking for full flight capabilities and retaken the skies.

This statement is utterly fatuous. Domesticated chickens can't survive in the wild, much less reproduce to the point where anyone would notice. I know this never made any impression on you when you posted as "Medved," but why make the same silly mistakes when you're tomzz?

What's next? A re-run of your minstrel dialect act and telling us how much you loved Amos 'n' Andy?

yes, that statement was utterly fatuous.
and, of course, one could observe that only a citified primadonna doesn't know that domestic chickens are quite capable of flight.
