How do you ship chickens?

[Nupine]

I have a lot of silkies for sale. 18. How can I ship them? Some are chicks, some are started, and some are 4 months old.

Simply put

all poultry must be shipped in approved USPS boxes.

All poultry over a day old must be shipped next day air (express)

Day old chicks can be sent priority (3 day).

Best pricing I have ever found on boxes http://poultry2.tripod.com/id3.html
I have never purchased from them so cant give any further information.
