Yes, the chickens drink from this, but not with enthusiasm. I followed instructions and removed their old waterer, then showed them (probably a hundred times) that they need to bump the nipples on this plastic box to get a drink. Just to be honest, they acted po'd. Well, the first day, I watched for hours. It seemed that some of the chickens decided they preferred death before bumping for a drink. It was over 100 degrees out, thus I became concerned that many were refusing the new contraption. I finally gave in and brought back the old waterer. Several little feathered fools ran toward it as if they'd been abandoned in the desert and suddenly saw a shimmery mirage of gulp-WATER!! WATER!! They drank up like little parched soldiers refilling empty canteens. I felt like a jerk. As the hot days continued, I laid aside the nefarious nipple nightmare. Finally, cool air arrived...yes, time to torture my birds again. (Keep in mind, this thing is meant for the farmer, as we tire of cleaning nasty waterers, thus my determination.) Once again, I took away the old waterer and replaced with the plastic wet nurse. Once again, I bumped the nipples in quick succession as about a dozen birds looked on. They looked at me like, "Not again, Karen!" I walked away, hiding behind a bush to watch. And yes, several took a chance on the nipple bump. Sure enough, other feathered friends decided to try it out, though some continued to be unimpressed to perform a chore in order to get a bit of water. By the end of the day, I decided to leave it in the coop as the only source of nourishment. Yes, bump or die...no alternative. The next morning, much to my surprise, all chickens were still alive. I heaved a sigh of relief! However, all day long I continued to notice the same stubborn chickens from the previous trial run were on a thirst strike, yet again. After several hours, I refilled their old waterer and placed it in the run...and again, the chickens-on-strike stood by eagerly as if to say "It's about time!" then heartily drank up the minute I walked away.
To conclude...we've all finally come to an agreement: Maiden Nippler lives inside the coop. Bump option is the only option once the door is locked. Once out of the coop, the old waterer is available as well-which they all seem to prefer. Both work, as Maiden Nippler serves my ultimate goal in that she stays clean inside the coop. I LOVE that! I see the chickens bumping her every morning as I walk toward the coop. No one has died, thus I surmise the chickens-on-strike must also bump while locked in their cell, though they aren't about to allow me to see them yield to such a secondary means for a simple drink of water.
