Love your poultry but tired of changing that stinky old water tank every morning? Let the Coop Queen help! With these 10 poultry nipples you can build your own system to deliver clean, non-poopy water to your chickens using ordinary hardware store parts, that can be re-filled from outside your coop! Our kit includes COMPLETE INSTRUCTIONS and 10mm THREADING BOLT. ***PLEASE NOTE: These Screw-In drinking nipples work best when screwed into bucket reservoirs. The will work in round pipe, but for the best fit when using 3/4" PVC use our SADDLE STYLE nipple drinker***
