It's a good thing to do when your hatchery tells you that your chicks have shipped, go warn your post office that they're on the way. If you have a good relationship with them, then many times they will call you as soon as they arrive (if that's what you want...sometimes it's pretty early in the morning). You can keep an eye on tracking to see where they are, but many times it isn't updated on the website in a timely manner, so be aware. Open the box in front of the clerk to check for losses--some hatcheries require a special form be signed by the witnessing post office employee to process any refunds for DOAs. If you live far from the PO, then bring a heat source and some water (preferably with a smidge of honey added) so you can immediately correct chilling and dehydration if needed.
