I am going to finally get around to hooking up my rain barrels this weekend. While thinking of where to put them it dawned on me to put one near the coop so I could simply divert water to my chickens instead of carrying it to them from the spigot until the weather gets too cold and everything freezes. Has anyone else done this. I am wondering if it is sanitary enough. I typically bleach my water-er and add about a half cap full to 3 gal. of water. It has stopped any diarrhea.
