chicken-slang?

[Lois Nathan]

Hi all,
     Could somebody enlighten me on the use of "chicken" in the following
stanza from Arlo Guthrie's 1960s song "Coming into Los Angeles", which contains
drug slang elsewhere.?   I've missed this one.

     Comin' in from London over the Pole
     Flyin' in a big airliner
     Chicken flyin' everywhere around the plane
     Could we ever feel much finer

     Comin' into Los Angeles
     Bringinn' in a couple a keys
     Don't touch my bags if you please
     Mister customs man

     etc...

Thanks for any help.
