i use the nipple waterers too. i got two from premier1 poultry supplies. i attach them to the wall. i started mine on them after about a week. then i take the other waterer away at about 2 weeks. i tap their beaks at the waterer, i show them how it drops down when i tap it etc and i don't remove the other water until i have seen them use the nipples. on hot days i always have regular waterers in a place or two for the flock as well as 4 nipple buckets. those ones at premier1 are the BEST i have seen. bucket nipple waterers. the lids fit snuggly NO dirt gets in and i fill it 3/4 full every 3-4 days...just to put fresh water in. there is never algae forming or anything! AND the nipples are recessed so you can put them down while filling and they don't get dirty or clogged. it has been the biggest time saver ever! and i am a nut over clean water....
