These automatic watering cups work perfectly with bucket-style or PVC waterers. Water stays cleaner than standard waterers, reducing maintenance work. Use these water cups in warmer months and swap them out with the freeze-free horizontal nipples for colder months. The cups automatically fill and maintain half-full water levels, providing constant access to fresh water. Hens can dip their wattles in the water to cool down during summer heat.

No learning curve required for your flock with these gravity-fed water cups. Simply drill holes using a 3/8 inch drill bit into your chosen bucket. Position holes at least 1 inch above the bucket base. Elevate the water bucket on bricks or platforms to keep cups above ground level. Adjust cup height to approximately your birds' back height for optimal comfort.
