Ducklings without electricity?

[HomesteadDucks]

Luckily we have power right now and the heat lamps are still shining on my day-olds. But there is a big snow storm hitting right now (and the snow is VERY heavy). I fear that the power will go out at some point tonight. So while I still have the power of the internet, does anyone have tips on keeping my babies alive without the heat lamp?
