I shipped several batches of day-old chicks last year, with no problems, just following the fairly simple USPS regulations posted on their site. 1) I'm now reading on several different sites that MANY zip codes (post offices) are no longer accepting live chick shipments at all. (some breeders who sell chicks online even have the numerous zip codes listed) 2) In addition, I've read that those who do ship must call a special number for "pre-approval" before shipping. I cannot find anything about either of these on the official USPS site. My local post office is not a good/reliable resource for information. Does anyone know what is really going on?
