We use the water nipples also. They make a huge difference. I start with both kind of waterers and by the 3rd day they have the nipple down so I pull the regular waterer. Hang it at eye level and their curiosity will take over and then raise it a bit so they stretch just a little bit to reach it. However, I do bump their beaks up to it a few times and let my finger catch the water next to their beak.
Yes, do this!
