Thanks, I won't throw this out yet - maybe I'll try it again in a few weeks. It sure seems like the chicks peck at the red area more than the silver nipples. I also don't notice any water around the nipples, which makes me think the water is not coming out at all - including the fact that the water line is not dropping. This is the unit I bought, in case anyone else has the same model, I'd love to hear if this works for anyone! https://www.farmandfleet.com/products/1063517-farm-innovators-heated-2-gallon-poultry-drinker.htmlThey may need to be a little bigger to trigger the nipples depending on how stiff said nipples are.
You can mark the water level to see if they're managing to drink when you don't see them doing it.
I find that any time I offer open water my chickens rush for it -- even though they always drink from the nipples.![]()
