Had to laugh at the title of my post. But in all seriousness- I have set up an nipple watering system and to accommodate them where I wanted them in the coop, the tips of the nipples ended up being 19" off the ground. I know others have said that it depends on the chicken, but I don't have adult chickens to compare this to. My babies are a RIR, Delaware and Gold Comet. What I would like to know, from those that already have a nipple system, is if this will be too tall for my birds when they reach maturity (until then I can improvise by putting something under it for them to stand on. I'm about to finalize the set-up and don't want to have to tear it down later. I searched the forum and couldn't find a satisfactory answer to this question, thus my new post. I appreciate any insight.
