Thanks again, all! We're going to be putting up an informational page on the site about hen growth and a how-to care page, and I'm sure some of the pics will go up there, as well.
My silkies were definitely "early to bed" on miserable winter days but could always be enticed back out for a treat.

And in case waterfowl are ever under consideration, many ducks are extremely cold hardy. Many refuse to take shelter on any but the most brutal nights. My Pekins had a cozy duckhouse available in their well protected pen, but would only retreat to it if temps were below at least 30degrees WITH sustained winds over 25 mph.
