I agree with Muggs. When eggs are shipped in sawdust/shavings (large amounts in box, not just to secure in carton) it makes the box much heavier, and then (if ????!!!!!,) WHEN it is dropped, there is a lot more jarring force to the eggs than if they were packed with paper and bubble wrap. I have received eggs this way with MANY detached air cells
