The OverEZ Chicken Waterer is the clean, convenient, watering solution for healthy chickens. This chicken watering device is great for both indoor and outdoor use and holds around 12 gallons of water. The OverEZ chicken waterer eliminates daily maintenance by providing clean water for up to a month. To train chickens, 1. Remove lid and add 11/2 cups of raw, organic apple cider vinegar (optional). 2. Fill with 12 gallons of water and replace lid, ensuring a secure fit. 3. Remove all other water sources and gather chickens around the waterer. 4. Tap nipples until water fills the cup (red color naturally attracts chickens). When one chicken begins drinking, others will follow. 5. Check water levels every 4 weeks and refill as needed. Discard any stale water before refilling. Blocks or bricks may be placed under the feeder to accommodate your chickens' feeding height preferences.
