Nipple waterers are just fine as long as you keep them clean and not frozen up . All depends on what the chickens grew up with . I made my own waterer out of PVC and the girls get plenty of water , BUT they do enjoy a nice bowl as well every day & I have cast iron pots out in the gardens when they free range every evening ...,.Woah - what an aggressive response! I thought nipple waterers were recommended for keeping the water clean. This was also the best reviewed heated drinker I could find. They don't need to "suck" on the nipple... just peck.
