Building an automatic chicken waterer
Have the water from the chicken house roof top collect in rain barrel to auto water the chickens
2-liter bottle of water in roof provides as much light as 50-watt light bulb. Saw a tv program about this and how people were introducing it to natives in poor countries who dont have electricity and can't afford solar since they live in shacks with thin roofs this was a perfect solution Ingenious! I will be trying this if i ever have a garden shed and/or chicken coop.
Did you know that 1″ of rain puts about 600 gallons of water atop a 1,000 square foot house? That’s a lot of rainwater to capture and a cistern can do the trick.
