Our beta rooster Johnny is usually the most curious of our two rooster and three hen flock, but Johnny took one quick look outside and retreated back into the hen house. This left matters up to the alpha male Boss ( a solid three inches taller than Johnny and quite a few ounces heavier, too). All the courage Boss could summon up enabled him to extend his neck outside the doorway (picture below), cluck fretfully, and retreat back inside.
After such a display from the males, Sweetie Pie, Baby, and Tootsie did not even peek out of the opening. All our chickens stayed inside until the weather warmed and the dusting evaporated.
