That will work great for a small flock. All of my coops have auto waterers. Good luck and have fun...
How do you keep the water in the pipes from getting hot? I was told that chickens won't drink hot water. I just cant figure out how to get over the sun baking the pipes that bring water to the coop. I thought of burying the pipes, but the water in the pipe that is in the coop will still be hot. There is not enough use to keep the water flowing. Moving water is cooler. We have 19 hens that drink about 2-3 gallons per day.
