I'm new to raising chickens. So new, I don't even have them yet! I bought a metal feeder but, after tending to a neighbor's hens a few times, want something that will keep water cleaner. There is so much information on this site that I am thankful for, but I'm having trouble with choosing a watering system. I keep thinking that something like a giant rodent waterer (not the ball type but the kind that has a small reservoir at the bottom) that could hang off the side and be too narrow for them to try to roost on seems good but I haven't seen one. Which means there might be a flaw in my idea. Narrow seems good because the run, now in process of being built, is only 3 x 10 and I'd like to not take up any more space than necessary. There will only be 3 hens. Has anyone seen this approach? Other suggestions? Very much appreciated.
