I hear how wonderful vertical nipples are and I'm considering switching. Right now I have a regular ol' automatic waterer that I made myself with a bucket and metal pan. I'm tired of cleaning it out. I live in a sandy area and as soon I turn around after I clean it, it's dirty again! I need advice on training my birds how to take vertical nipples. I have 5 laying hens (ranging in age from 1 to 4 years old) and I recently got 8 chicks this past weekend.
