I am anticipating the arrival of my baby chicks tomorrow from Healthy Chicks and More. Typically when they arrive in town, what does the Post Office do with them? Do they call me for a pick up? Do they attempt delivery? What happens if it is getting late in the day and I don't want the birds to be in the box for a third day and I haven't heard from USPS? The hatchery did not spend the extra $1.50 for tracking.
