Yesterday my turkeys were due to arrive, and the PO did not call by 11, which is usually the latest I expect chicks.
When I called, the temporary postmistress said that no more could be expected that day. WORRY WORRY WORRY.
Then I got a call just before 6 pm that they came in on the last truck. Luckily I hadn't gone into the city or something. I rushed out -- the employees stayed for me -- and got them home. All are fine. They didn't have to spend an extra night in their box in the PO.
So make sure your PO has your cell number, and stay in the area. Or stay home if you have no cell.
