This is an ad on my local craigslist. Not that I am interested in buying them, but I though $100 for a chicken was ridiculous. Do people really get this kind of money? Full Blood Serama Banties - $100 These birds are very rare and can be kept in house for house pets. Very tame if you keep working with them and handling them. full grown rooster wieghs only 12 ozs. Very attractive birds. Not many of these birds in the United states. 2 sets of parents on premises and chicks hatching in incubator about every other day. These birds sell fast.
