I'm sorry I don't have any pics now but will try to get one. I have a 5 gal bucket on a shelf outside the coop. I run a water hose out of the bottom of the bucket through the wall of the coop. To that I have attached a piece of pvc using a 90 degree elbow at the hose/pvc connection. The pvc is attached to the wall of the coop to avoid any roosting on the pipe. My piece of pvc is only about 2" long but the same idea could work for any length of pvc. I have 4 nipples attached to the pvc for 9 chickens. By attaching it to the wall and by using flexible hose to put it together, I can adjust the height for the different ages of the chickens. All I have to do is check the water level in the bucket and fill it with another watering hose outside the coop. Works great for me.
