They do fine. I will put fresh water in the pool before shipping so it is watered good first. Get it to the post office before 8 am. On the third day it will be held at the post office for you. They will call. I just wait untill the open, and they are out of the box sooner.
That is really only 1 day without water. You make sure they drink plenty before taking to the post office (day 1) they are in transit the next day no water. ( day 2) the third day they are at the post office waiting to be picked up that morning, and you give them food and water right away. So they only go one day without. It will be fine. There are little water bowls attached inside of the box so that helps too. No worries. Plus they are actually carefull with the live ducks. They can hear them quacking inside. There is a little windowed they can look into to see the duck.
