I posted on here about a month ago with pictures of the nipple system I wanted to put in. Just to update, I put it in a week ago and just turned loose about 400 chicks and it works great. They just peck it and the water comes out a drop at a time. No leaks into the bedding and they get plenty of water. I will post some pics if anyone is interested in the one I built. I bought 40 nipples and installed them in about 17 feet of 3/4 pvc.
