- Intuitive design: pressing the nipple releases a few drops of water, reducing waste and helping keep the watering supply clean. - Easy DIY installation: drill 1 inch from the bottom of each bucket, then use the included installation tool and wing nut to secure the nipples. Important: the rubber seal must be placed outside the bucket to avoid leakage. Do not place the rubber seal inside the bucket. - Versatile and safe: nipple feeder is food grade BPA free and fits most containers, including buckets, barrels or troughs. Using larger containers helps it stay full longer. - Complete pack for poultry: comes in a pack of 20 and includes drill, installation tool, rubber gasket and wing nuts. Suitable for all poultry, including chicken, duck, quail and turkey. - Use scenarios: - Backyard coop with standard buckets to minimize waste and keep water clean. - Farm setup using barrels or troughs for longer refill intervals. - Mixed poultry pens sharing a single water source for multiple species.
