Shipping live poultry in the United States is a relatively unique service offered by the US Postal Service (Fedex and UPS do not offer it). The USPS will only transport live birds only along pre-approved shipping routes for the safety of the birds.
The process does not conform to the normal time frames that you may be familiar with. Normally, USPS Priority shipping takes 1-2 days, and USPS Express shipping takes 1-2 days.
Usually, an order shipped via Express will move along the exact same shipping route, at the exact same speed, as an order shipped Priority. We always to ship Rare Adult Birds via USPS Express shipping for added protection, but everything else we send Priority.
