This winter can be a curse or a blessing, whichever way one wants to look at it. As a blessing, it can show one where there are gaps in their livestock systems that need filled before another such winter as this. As a curse, one can just see it as misery and not much else.
Back in the day we didn't have electricity and our water was carried from a spring that was a little distance from the house. We had to break ice each time and carry water to the house via buckets and milk jugs, then a couple of 5 gal. buckets another 200 yds to the pigs and chickens. That was the job of my sister and I before we went to school and again when we came home again...I was 10, she was 12. That was a cold business and you couldn't avoid getting your hands wet when dipping from a spring.
The pigs got water in their slop/feed, so we knew they were getting enough water with their food. We didn't try to give them extra water beyond that. Seemed to work...they ate it all before it froze and all the water was gone also.
The chickens seemed to get enough water before theirs froze up each day, so we didn't worry about them either. Water and feed twice a day and that was it.
Back in the day, folks would serve the livestock some warm gruel or mash when temps got this bad, so they got their water and feed in one meal. Seems like a good idea to me.
I feed wet feed to the chickens all winter long, so even though they have a heated dog bowl of water in the coop, they rarely take the levels down at all. I keep it from freezing by feeding it on the earthen floor in the middle of the coop, after I've raked back the DL there. Keeps it from freezing before they can eat it all...they get fed once a day in this manner and they seem to be getting all the feed~they are fat and sassy.
Lately I've been carrying hot water up there to pour over the dog's food, stir it up to make a gravy and feed it to them that way. I've noticed a lot less water use in their heated bucket since I started that, so I'll continue that for these really cold temps.
What a luxury those heated buckets and bowls are, though. Takes a lot of the work and worry about winter water out of the equation, so I highly recommend them. Used to have one for my sheep too. When the power goes out, they aren't much help, though, so feeding water and feed together can sometimes get the animals their daily water needs when water is hard to keep liquid.
