Rotating nipple waterers can work just fine, bring them in at night,But i would still fight the freeze. Does anyone have 2 or 3 - 5 gallon bucket setups with nipples and rotate during the cold or not worth it?
then rotate as needed during the day...if you're around enough to do that.
I rigged a mesh stand on top of the boiler to thaw them out faster.
You can put the HN's in any vessel if you're careful.
Here's a couple of ideas:
