I put in a few chicken nipples (from cconly.com) in a 5 gallon buckets. The chickens took them to immediately. However they seems to be rather messy waterer. Everytime the chicken "drink" from them some water would drip down to ground. Am I doing something wrong? Obviously the nipples themselves are not leaking. It is really bad right now since I am putting the water bucket in my wood shaving covered coop, and it is making the wood shaving damp. I plan to eventually move the waterer outdoor when the run is completed, but I am still concern about how much water is wasted instead of drunk. Thanks.
