Need some help/advise. I am currently using a 5 gallon bucket flipped upside down in a feed pan as a waterer in my runs. It works well, BUT, the silly chickens stand on the bucket and of course, the water winds up with poop in it. So, it kinda defeats the purpose of having a bucket that will hold water for a couple days. I have seen a few pix of a PVC type waterer, but can't remember where nor the instructions on how to make. Anyone have suggestions? THANKS I am getting ready for a 3-4 day hunting trip and want to make sure the chickens are taken care of while I'm gone.
