We have a stock tank heater in the bucket and it works very well to keep the water itself from freezing. When we get our super cold days - those days when it's -17 or colder - sometimes the little catch cups under the nipple mechanism will freeze in the overnight hours. When they do, it's something to see. The little bit of water left in that tiny red cup will freeze, and that ice sometimes forces the metal trigger open. When that happens we get the prettiest icicles from the nipples, down the bricks the waterer stands on, and onto the floor right in front of the waterer. So as long as I'm going out to the coop first thing in the morning anyway, we just grab the heat gun. Takes just a few seconds to thaw each nipple and we're back in business. In fact, that takes less time to thaw the icicles than it does to dump a frozen pan of water and refill it. The nipples don't freeze during the day when the waterer is being used regularly, just during the night when the chickens aren't drinking.How hard is it to get them used to a nipple system after using hanging waterers? I would have switched already but it actually looks like more hassle than just refilling a 5 gallon bucket with a hose...
I like the cleanliness of the nipples, but I have a hose in my hand most if the day anyway, shooting water to into their bucket us just a swish if my hand lol... Winter is a different story; I can't get anything without a heater to stay thawed longer than 4 hours....
@Blooie how do you keep your water thawed up there?

Thawing the nipples on the waterer. Just takes a few seconds for each nipple. We start with the cup area first, then hit the icicles.

Here the cup has been done, but you can see the icicle going down the brick.
Despite having to go out there and do this, I'd still rather use this system than anything else. The nipples don't freeze up on us except for a few days each winter when we get our sub-zero spells. We had a long discussion about this somewhere on the forum last year and this year the new bucket has the nipples up higher on the waterer. Don't know if that will eliminate the issue, but lots of folks in that other thread thought it might so we're trying it. If it works, great - if not, we're no worse off than we were before. Another thing we are doing differently this year is keeping the water bucket out in the run rather than in the coop. The run is covered with clear greenhouse plastic during the winter and is usually warmer than the coop because of it. So we'll see.
I guess I was not fully understanding that the water in the line for the nipples was coming from a bigger source...one that a tank heater would fit in obviously...
I was overthinking it, as usual lol... It's worth a shot, anyway, no sense in not trying.... Seems that if I REALLY didn't want to put up with ice, I would move eh?
