Up for sale is our 2 head poultry nipple drinker. Well suted for around 6 birds in an urban coop or hobby farm setting. This drinker uses two 360 degree ultra flow screw in style nipples. Each nipple has a 360 degree stainless steel nipple head that will operate from any angle. Top quality brass water connection fitting connects to a standard garden hose thread. Poultry watering nipples work under low pressure only and cannot be connected directly to house pressure without a regulator. Typically most people use them as a gravity fed system. Simply connect it to a hose that is connected to a bucket, 5 gallon pail, 55 gallon drum that is above the level of the drinker. Fowl learn to use them in minutes, whether they are a day old or 5 years old. Works great for broilers, breeders, layers, pullets, chicks, ducks, and other game birds. Typically this is what professional chicken farmers use and they use them for many reasons. No poop in water so it is sanitary. No cleaning dirty waterers every few days. No spilling and soaking the bedding/nesting material. Clean fresh water can be ready on demand stored in 5 gallon to 55 gallon storage drums and be gravity fed to the 2 head poultry nipple drinker. Manufacturer recommends 1 nipple per three birds. From my experience you can go up or down a few on this number if they can all get a drink when they feel like it. It is optimum at 3 or less per nipple to avoid lines and arguments if you let them out where the water is every morning. Again, water nipples work under low pressure (5 psi or less). If you are wanting to connect it directly to a garden hose (house pressure) you will need a pressure regulator to regulate the pressure down. House pressure can be 30 to 70 pounds of pressure, you would need to regulate it down to 5 psi or less. Otherwise your birds will get a shower rather than a drink and it can cause damage to the nipple.
