Neither Fed Ex nor UPS will ship live baby birds, so we ship all orders of fewer than 15 chicks via the speediest service that the Post Office offers for baby chicks: USPS Express Mail.
Orders of 15 chicks or more are shipped by USPS Priority Mail. Your chicks can arrive any day from Tuesday to Friday of your scheduled shipping week, assuming that they ship on a Monday. (Our chicks almost always ship on Mondays, unless there is a national holiday that Monday, in which case they will ship on a Tuesday!)
Exactly which day chicks arrive at your location will depend on which day they were hatched, and how quickly the Post Office services your area.
