I built a automatic waterer using water nipples. I know for sure that 2 of my 4 chicks (8 weeks old) know how to get water from the nipples. I'm not sure about the other 2 though. I'm kinda scared to remove the 1 gallon watering bowl because I don't want them to not have water if they need it. Am I just overreacting or will they find the water from the nipples if they needed it? How have you all trained your chicks to use the nipples? Will they learn from the other 2?
