What I do is hold each chick and quickly dip beaks in the water and stand the chick up in front of the water. Sort of skim the surface of the water with the birds beak and usually they naturally open their beaks and get water. And this way they know where the water is. Same with food. Lay out a paper towel with CRUSHED crumbles on it and tap with your finger until they understand were the food is. Crush the food if it isn't already, for several days, using a paper towel. Eventually they will learn where food and water is. Chicks rely on mom to show them what to do.
