In our multiple attempts to get our girls set up with a non-frozen food and water for the winter, I found horizontal nipples on a thread here, and they work great! The only problem is the chickens WILL NOT drink from them! They had been using vertical ones, but they leaked. For several days they were getting their water from the fermented feed I was giving them twice a day (in a heated dog bowl with extra moisture to keep it from drying out). Once we realized they weren't drinking from the new water bucket, I tried numerous times to show them how to use it, even getting them to peck on them, but they just wouldn't drink from it! So there hangs the bucket they won't use and I went and bought another heated bowl so they have one for food and one for water... Has anyone else had problems getting their girls to use the horizontal after using the vertical? So frustrating!!! Is there any point to leaving it in there, hoping they'll come around?
