A few regular, nice, backyard chickens are the ones sold for $20. I personally think any mean bird is best in a stew.
ETS: Also if these birds were really close to the breed standard there are enthusiasts out there willing to pay $200 for them. Out in west Texas some birds are known to go for close (if not over) $1,000!
I had no clue what they were. I know the people thought they was goin to get good money for them. But, I also thought I was going to get better than 50 cents each on 2 buff orpington roo's and $1.50 for a hen and roo in silver laced wayndottes.. LOL
