As a postal employee I say complain. Complain to the postmaster, ask for the phone number of the district or regional manager. USPS is trying to improve customer relations and the only way the people who can actually do anything will know if there is a problem is for people to complain. Now don't start yelling and screaming. When you go in to finally pick up your chicks do this. Have the tracking info printed to show the detour, calmly ask to speak to the supervisor or postmaster. Explain calmly that this was a live shipment and is very time sensitive. If you have not done so already open the box and explain the general health of the chicks. Explain what the chicks should look like when they have benn recieved in a timely manner. Ask why they were missent, ask what the P.O> is planning on doing to keep this from happening again. Let them know that this is not an isolated incedent. If the person that you speak too is not receptive ask for the phone number of their supervisor. Do not just give them your number for the higher up to call you. If they are receptive ask for their number to call back in a week or so to find out what they plan on doing to prevent this again. I know that this won't help this shipment of chicks. It might help future shipmaents though. If they don't have an answer on what to do prevention wise in a resonable amount of time ask for the sepervisors number and work your way up the chain. Contact the shipper also and ask them to contact the post office for an explenation. If you have to talk to a district or regional manager have the shipping info as well as the time date and name of the person you talked to. Be a very persistant polite bur under their saddle.
