I'd have some electrolyte power to mix in the water, sometimes the trip is rough on them. Sugar in the water can give them a needed boost. Make sure no newspaper, it's to slick for them, paper towels work well for the first few days. Don't feed grit right away, stick with the starter feed, it's all they need. Let them get to three or four weeks before the treats start. Depending on the type of waterer, you might want to drop in some marbles in the water area to take up space. I know it sounds dumb, but the chicks can tip over and drown in the water.
I had 21 hatch yesterday, they're in the brooder now which was just abandoned by the earlier 72 from the hatchery
