A week ago, we installed a five gallon bucket with three nipple drinkers on the bottom. The bucket is hanging in the chicken yard; the bottom of the bucket is approximately a foot above the ground. So far, our hens (and rooster) have totally ignored this new source of water. Because it's been hot, I've been reluctant to remove their old waterer. However, I really want to discontinue using the metal waterer. Does anyone have any advice about how to teach chickens to use a nipple waterer? Thanks!
