i buy and sell on craigslist. i recommend that you "go to look" at something. then you feel less obligated to buy if they don't look healthy. sometimes i agree to buy and just go to pick them up, but you don't know what you are getting even if there is a picture. watch out for runny poop and other signs of illness. calling and talking to someone gives you a lot of info into the type of person. some people are just into pets and get bored and change, but most are culling their flock. i have bantams that are super broody so i let them raise chicks. there is always a market for layer pullets. private sales give you more time and info than auctions usually. i have had mostly good dealings on craigslist and found it better than on-line auction sales that take pay-pal.
