I'm playing this game right now. When I put the nipple bucket out there, they all went after it and were using it fine. Then, I added 7 pullets that had never used a nipple waterer, and I have been giving them a bucket of water just to be safe. Now nobody wants to use the nipple one, and I'm pretty sure they basically didn't drink yesterday until I came home and gave them a bucket. Not sure if pushing it to two days will force them to use it again or just make them miserable... Gonna play it by ear.
