Gene Logsdon, The Contrary Farmer
For many years I could not understand why the sound of singing hens soothed me so much. Hen song is hardly melodic, being composed of two or three notes at most. It is plaintive in fact, a far cry from the bubbling warble of a bluebird or the soaring lilt of a meadowlark. Hen song is plainsong, equivalent to the way any of us might hum our way through the humble chores of daily life.
