I agree with Snowbird. Their birds may not meet the quality and standards laid out here on BYC but II don't think they are really misrepresenting the birds, just talking them up - perhaps way up. Most of the birds sold around here, on craigslist or otherwise are hatchery or hatchery-like stock. Folks learn soon enough, if they want to, how and where to get quality birds (I had to take that journey myself) and not everyone is wanting to be a 'proper' breeder, some folks just want to sell chickens and some folks just want to buy chickens. Plus craigslist has some 'interesting' folks that I really would not want to invite into my personal life.
Today is a gorgeous day here in southern NH. Gotta get outside. Have a fun day all!
eta - I sell all kinds of stuff on craigslist so I guess I'm including myself there too....
