Did you even look at the thread discussion I cited?
People expect some little internal space heater to kick in just because they throw them a handful of corn at roost time. Way back when, I heard that myth repeated over and over again,too, then was made aware of studies that concluded otherwise. A dry environment goes a long way toward making the flock feel warm during a cold night rather than what they eat at roost time. Moisture brings in the chill to a coop and with it, frostbite.
