Chickens are not going to let themselves die because they don't like a particular waterer. When they are thirsty, they will use it, but only if it's the only source of water they have. I put some 3 month old chicks in my coop a couple years ago. It was dark already. They were used to water in a dog bowl. When I checked on them at 6 am they were all getting drinks already. I have never showed a bird how to use nipples and have never had a bird not use the nipples.Yep, exactly what mine do! Very frustrating since that means they know HOW, they just WON’T.
