The other day I found an old box of demo waterers from a poultry show at an office were getting ready to move out of and threw them in the back of the truck to try them out and BOY have I been satisfied. They're only distributed to "bigger than backyard-chickeneers", but if you EVER come across something like this I would totally recommend trying it out! The only downfall is that if the pipes freeze - you're in the hole! They're made by a company from Goldsboro, NC (I think). But here goes the description: I installed it in my coop/chicken shed so that I can regulate the pressure, connect a hose, and get water from another source in the coop! I'm going to put a few pictures in here and sorry if they're not rotated correctly but you'll see the general idea. Also this is just a recommendation for an easy way to water 20+ chickens, not a marketing campaign! And please excuse the leaky hose, it's fixed now but took a little Teflon tape to get the job done! Here's a Picture of the hose connecting to the PVC Plumbing (Ball Valve, Pressure Regulator, and PSI Gauge shown): This is the actual waterer - the water comes out of the holes in the top. (kinda have to clean them out occasionally): Piping to the roof with on off switch connecting to PVC (sideways): They're really handy if you have to leave 3 weekends out of a month.
