chickens and mail-men

when i call the post office i get the voicemail....
i called the hatchery and all 52 chicks were mailed out yesterday and should be here by now. this happened with the last batch. the mail came with no chickens arriving with the letters. then at 1pm, the post office calls saying they have the chicks, but the mail truck would not be able to bring them until the next day, but which time they would have dehydrated and died, so i has to rush to get them, bring them home and get them settled, then rush to get my kids at school.
it looks as though the post office is not even calling this time.....
WHERE ARE MY CHICKENS!
