I can't seem to find the horizontal nipples sold as singles (without paying high shipping costs) and Amazon only sells packs of 5 for about $17. I only need one, or possibly two even, for my 6-hen watering bucket. But I don't want to pay for the extras if I don't have to. I found some singles on mypetchicken.com, but again the shipping was more than the nipple itself. Any ideas? Thanks! Edited to add that I have tried three different local feed stores and no luck - only vertical nipples available.
