i hope they work ,i,am sick of carrying water feeders out to coop.
They work great! No more dirty water! I fill up the buckets about every 10 days or so.
For the transition for your birds, the important thing is to remove ALL other water sources. Then wait till they get thirsty and go in and activate a nipple to release water and make sure a chicken or two sees you do this. It won't take long for one bird to figure it out, then the rest will soon follow. It took our chicks a couple hours for all them to figure it out and our adult birds took most of a warm day (some took 1.5 days). If you leave any other water source around, they won't bother drinking from the nipples if they can get water easier somewhere else. Unless it's 100F+ there should be no harm letting them get a little thirsty while they figure it out. Of course, if you have any sick birds, treat them separately...probably not the best time to teach them nipple watering until their healthier.
