I did a search and couldn't find a clear answer to this question. How big a waterer does a small flock of 4-6 hens need? The obvious answer is "plenty" -- especially in central NC in the summer. But how much is "plenty"? I'm thinking a nipple system. I always put my cockatiels onto water bottles because they foul their water in no time flat and I'm sure chickens are no different, except for being big enough to spill the water outright. And, of course, a minimum of two nipples in case one is clogged or a dominant animal tries to prevent a low-ranked one from drinking. I want to be able to fill the reservoir no more than once a day and, optimally, to be able to take an overnight trip without worrying about them running out. Likewise, how big a feeder would the same flock need under the same circumstances?
