They don't seem to know, so I thought maybe someone here might Shipped eggs on Saturday, like we have done many times. This time we got them back, as "there are no flights for hatching eggs until 5/4" Talked with 3 very nice postal employees, who tried to tell me everything they knew, however they were unable to answer the question "Can I still ship eggs on Saturday, or has there been a regulation change?" So far, 3 phone calls, a face to face, and no answer................ So, let's review, We can ship on Monday thru Wednesday and have a reasonable shot at eggs being delivered in a timely manner. Thurs out Friday out Saturday?? Usually Saturday equals a Monday delivery, now, who knows?????? I have been told I need to speak with "Mailing Requirements" who does not answer the phone. Maybe I need to write them??? So, Raven1, your eggs did ship, and will ship again Wednesday.
