I was hoping to find something different in the other thread on winter watering ... but rather than drift that thread I thought I'd start one with my own questions.
This is my first winter watering animals (well, last year we watered the bunny - we kept one water bottle inside and when the one outside froze, we swapped it for the thawed one from in the house).
Now I have a few sheep, who need more water than a bunny.

I will have to carry water from house to pen, because I haven't got any power or running water where the animals are (I have a garden hose, but that'll freeze and burst in no time flat, so I'll have to just use the faucet).
I am considering some ideas I read about ... putting an old tire down (up off the ground would be best I am thinking), filling the rim with rocks, shoving a black rubber bucket in it and putting water in that (the sun warms the tire, rocks hold the heat, and all that helps keep it all a little warmer and not freeze up quite so fast) ... then I also thought, if I'm running the wood stove in the house at night, maybe put a couple of rocks on top of it to heat during the night and in the morning drop them in the water bucket along with the warm (fresh) water brought from the house, to add some warmth and keep it all liquid a bit longer.
I've heard floating a stick/log in the water helps keep the surface from freezing ...
Anybody got any other low (no) tech ideas for watering animals in winter? (and I mean real winter ... note where I live

)
