Frost???? We are -25 F actual right now with a -35 F windchill. And people wonder why I have a good heating system in the coop "just in case".Frost on the lily pad - good morning Pond.
Worst is, have to get ready to leave for a dr appointment soon. They've closed THE school (yep it's a k-12) because 90% + of the kids ride the bus and this cold it's just too risky if the bus should break down or get stuck. Not to mention some of the kids have driveways up to half mile long they'd have to run down. I think they close if it gets below -25 with the windchill.
