Chicken Nipples

I had heard these things were great. "You won't have to change dirty water for a week at least." "Chickens learn how to use it in just a few minutes." " It's the best thing ever." Well, my chickens must be DUMB! I ordered 10 of them. My husband figured out how to get them in the bottom of a 5 gallon bucket. We hung it in the chicken house at about 12". Filled it with water. Stepped back for the stampede. That never came. Because the chickens have YET to even see the red nipples hanging from the bottom of the nice clean water bucket. And I am using the water from that bucket to fill up their very dirty water bowl a few times a day. What a waste of money. Well, they weren't that expensive, but still. I ordered 10. Used 4. I was going to use them for my meat birds too but I guess I'll be filling up more water bowls for them too.
