someone had chicks shipped but didn't actually pick them up.
I wonder if what happened to me happened to them -- there was a typo in the phone number on my box.
Fortunately, the route carrier was in the sorting area and, being a personal friend of my SIL, she called my SIL and my SIL called me.
Though if I hadn't gotten a call by noon on the day I was expecting them I'd have called the post office.
