I sold my rare-breed Large Fowl Wheaten and Blue Wheaten Ameraucanas (I may be the only breeder of these--There might be a couple more?--in Utah & Idaho) at $10+ each last year in Idaho. I sold a Frizzle Cochin-Polish cross roo for $20 two years ago. Hopefully you can get $5 each or more for your Polish roos.
A good place to get a good price, I've found, is selling them at the county fair. At least at the Franklin County Fair, you get $1-2 each just for entering them, and MANY people want to buy at the fair. I put a note on my chickens' cages that they are for sale and their prices. I've especially been able to sell well on the last day of the fair, because some people don't come to buy until the last day and then most of the low-price chickens have already been purchased and if people really want a chicken they're willing to pay more, especially if it's a fancy one.
