I know that once they ship, you are supposed to tell the post office to call you so that they don't leave the box to be brought to your house! I might order mine so that they come on the weekend, because my parents won't let me skip school to pick up chicks, and I don't trust them all that much to know what they're doing. Having electrolyte/nutrient water for just in case seems like a good idea, instead of waiting until they actually need it. Do you show them the chick food with their beak the way you do with the water, or just place them near it? Do you use a gravity fed chick feeder or one of the long ones?
