I have a few questions we just bought some poultry nipples and put them on a 5 gallon bucket then i took away their other water and left them with that one they all pecked at them and an hour later i put the other waterer in and they all started drinking like they didn't have water for the past hour. Do they just need to learn how to get the water into their mouths or what. Also is 16% crumble good or does it need to be lower or higher. Also can i feed my chickens corn if i do a 1/4 corn ratio 3/4 feed?
