Where do you get these numbers? I don't have any statistics handy myself but those numbers sound far to high to me. I feel like if that were true they probably wouldn't allow shipping through the usps. I have only ordered chicks a handful of times, but I have rarely lost more than one or two during shipping and have never lost shipped chicks more than 24 hours after deliverySomething like 11% die during shipment and 50% perish within a week.
