Verticals are often leaky, not good in your cold climate.Yeah, mine are in the bottom of a 5 gal bucket.
I mention because the first year it took me a few tries to get the height right.
I tried to have the nipples at eye level, thinking if they saw the red plastic it would give them the idea, since the chick waterer was red. This was too low. It went a lot better when I raised it maybe 3” (when they were young) above eye level. Then they could get their heads up.
Must be a commercially built with heater in the bottom?
