What I did when ordering a variety that I wanted, 10 chickens of 5 varieties, I filled in my order with the Calif White males at 58cents apiece. I then arranged to give the extras to my feed store that had chicks. You might even be able to work a deal for a bag of feed in return or something. I figured it was just part of the cost of getting what I wanted vs buying the ones at the feed store, usually RIR, or Barred Rocks. I love them both but wanted a different variety.
You can also contact your feed store and often they will order the ones you want to include in their order and the cost is much less. Or is you can find someone nearby you can share an order.
