hi everyone! I have a chicken who decided for some reason or another she would rather sleep under the stars last night than in her cozy coop...and it was near -20 f last night. She is currently inside hanging out with us, but I wonder if its necessary? The coop is insulated and has a heat lamp for those really cold nights (-20 is an average temp lately) and during the day its roughly -10. Does she nèed to be inside to recover? This isnt all that severe of a case, is it?
