A Bit Chilly

Had a few cold nights this week. Now last night it only dropped to -6.7 degrees Fahrenheit, and in December we had already gone as low as -10.6 f so that wasn't very bad. But night before last we achieved a bone chilling -20.4 f! (And Tuesday night -16.1 f.) I know it gets colder in other parts of the country and the world but for this part of Michigan, that was pretty significant. I was sure yesterday morning my chickens would be little chicken-sicles because the coop had dropped to 6.7 f even with the 250 watt heat lamp. At the very least there would be frozen toes, but they were fine, just very quiet.
