Someone posted photos of their coop that had an adapted red cooler as the water source. Thought I had saved it but hadn't so I searched the site and now cannot find it. Found some great incubator adaptions but not the waterer. Since it was a design/construction post, I post here rather than the feeding/watering section. Any reason one couldn't add Tek Supply nipples to a cooler the same as to a 5 gallon bucket? The cooler would keep cold water and ice longer than the uninsulated bucket. Thanks!
