My question now is this......Since the lady that MissP talked with seemed to be untouched at al about the situation at hand, then is she (the lady at McMurray) even sure that the birds were even sent?
This could be a possibility. Actually, I hope that this is what has happened. Just call Monday and ask them when will your order of chicks be sent. Maybe they put you down for the wrong week and the lady just assumed that they went out earlier this week.
Just a positive thought.
P.S.~~but if they do arrive, I would take a camera, open the box, take a picture and any that may still be alive that could possibly be saved, and then return to sender and ask for a refund, NO CREDIT, a full refund and plus the chicks you ordered.
