Chicken tractor watering system in our new Chicken Chuckwagon Coop-DéVille chicken tractor. Chuckwagon because of the on-board food storage area, where there is a handy feed chute to take the chicken feed down to ground level, and Coop-DéVille because it really is the Cadillac of chicken tractors.
We didn't want the mess of having the water inside the coop where the chickens could stand in it, knock it around, and poop in the water trough. Also, being accessible from the outside means you don't have to get into the coop each time you need to clean the water and refill.
Plans for this chicken tractor and the watering system are available at http://FarmLifeAcademy.com/chickentractor.html
