We're about 6 mo. in to our chicken watering with poultry nipples. I'm not happy. I like them for chicks in bin brooders because they're much less work than constantly cleaning out wood shavings & refiling water dishes. In my larger coop though, they are now failing. I'm finding that they are leaking. Dripping just enough to make a nice large wet area on the floor of the coop. So I have to move them outside. Which is fine. I've also found that all nipples are not alike. Some are better, some seem to leak no matter what. Anyone else have leaking poultry nipple waterer issues after time? Now searching for a reasonable way to keep the flock watered and also not have frozen water in the winter. The nipples froze daily in the winter.
