Where did you get the flag? My Columbian Wyandotte is also named Dorothy, but "Dorothy Gale" from the Wizard of Oz.
I got it on eBay. They still have a few more: http://www.ebay.com/itm/LE-POULET-C...=632629708079554608&pid=100015&prg=1006&rk=1&
My Dorothy is named for Dorothy Zbornak from The Golden Girls because her feathers are the color of Dorothy's hair, she's bigger than all the others, and she's bossy.
