"TIMBERVILLE, Va. — The barn where David Hughes raises chicks on his Shenandoah Valley turkey farm smells mostly like the wood shavings he spreads across the floor for bedding. And that may be an important clue in a farm regulation battle that's about to come to a head 118 miles to the east in the nation's capital.

'It disperses so fast,' said Hughes, whose farm sits on a back road along the north fork of the Shenandoah River and near the tiny New Market Airport, used for private airplanes and skydiving.
