Please remove all other water sources from your chickens. Fill the waterer up with water. Press the yellow tongue on each outlet to load with water. Every time you go into the coop for the first few days, keep pushing the yellow tongue. The chickens won’t take long to realise how to get the water and as they peck around in the water the yellow tongue is activated, and water is dispensed. Don’t be concerned if the red water cup looks empty. While the chickens aren’t drinking, the water can evaporate from the cup. They still use the yellow tongue to dispense when they want water. It can take the slower chooks a week before they get the hang of it, but rest assured once one cottons on, they all pick it up quickly!
