This soda pop bottle waterer is such a simple but brilliant solution for keeping your poultry and small animals hydrated! Made right here in the USA, it features a unique plastic strap instead of those rusty metal springs that always break. It hangs on the outside of your pen and projects through about 2 inches, fitting perfectly through 1x1 inch wire openings. Cable ties are included to secure it tightly to your bottle. The white color helps keep water cooler and fresher by reflecting UV rays. These are boil and freeze resistant too, so they hold up great in different weather conditions. Super useful for chickens, quail, rabbits, pheasants, waterfowl - pretty much any small farm animal. Now important note: these won't work with those new eco-friendly bottles that have shorter caps - the threads are too short to reach properly. You'll need to use older style plastic bottles or glass bottles instead. I personally love using glass bottles with mine. The hanging design means less dirt gets kicked in, no earthworms crawling in and dying, and it keeps vermin and insects away from the water source. Fresh, clean water means healthier, happier animals - and this simple waterer delivers exactly that!
