SNOW, boredom, no dust baths, grit? advice?

For now, it IS amazing how happy they are to come out when I can shovel down to dirt. The cabbage in the henhouse is like a big hanging bowling ball that they have barely looked at except to wonder what on earth is it and why is it in our house?

It is 15 below right now (10:30pm) and supposed to get as low as minus 24. Is there a temp. at which it is just too cold for them?

I was wondering this myself- how cold is too cold for a chicken?
All you Northerners... Is there a temp where we should break out the heat lamps?​

We have a sensor in the coop. It registers and transmits to the computer in here down to 0 deg F. When it gets below -10, it sends gibberish. When the sensor reads 1 deg, the heat lamp comes on for - ummm- a while? I don't remember what hubby has that set for.
