Make sure the is an air hole in lid if using horizontal nipples as we found out water was not flowing without a hole. ( Lid was too sealed and water wouldn't come out when they depressed plungers.
I made that mistake with my first nipple waterer too!
so that stuff isn't kicked into the feeder. Try a height and watch them eat/drink - if they seem to be struggling, adjust. If they're not - you're done.
