I have to agree with ChickenCanoe on this.
While there are some great PVC waterers out there, here's a simple PVC waterer and gravity-feeder I made for our flock while we were gone on a 2wks family vacation. Luckily, came back and all chickens were accounted for, nobody cried
fowl that they were dehydrated or starved.
Dogs were also watered/fed to similar setup, except I think they whined a little when we got home.
Anyhow, this is a picture of my test (demo) setup below, this setup has been modified to collect rain run-offs from the lean-to that's standing next to.
In the winter, I plan to move this setup inside the chicken coop and put an aquarium water-warmer in the bin so the chickens can drink. It's simple and mobile, within reach of a water-hose too.
Below is the gravity-feeder: (same 32 gallon bin).
For the openings, I use 3" PVC 90 degree elbows. I got the idea from Youtube but there are several great articles on this forum from our very own BYC'ers.
