I sold a few of these at our last Chickenstock. If you bought one I would love to hear how they are working out. I just put one up in our brooder box with week old cornish rock x's and they took right to it. With these waterers we take each bird and tap the nipple with their beak so they know where to get the water from. I am selling them for $10 a piece plus shipping. They hold one gallon of water. We have 14 birds in the main coop and I have to re-fill two of them every three or four days depending on how hot it is.
