I'm not sure if that's what these are called, but I'm thinking of putting those waterers with the nipples in for my older pullets (two weeks) to help keep the water clean for longer. My concern is that they have been used to the regular kind where they just dip their beaks in and drink and I don't want them to die of thirst when there's water right there for them. How do you teach them to drink out of those things? Is this age too young to catch on? And does anyone know how much water chicks this age should be getting each day? I was thinking about installing two 48oz waterers for 14 chicks. Thanks for any advice!
