This paper clarifies the characteristics of the shell egg market, particularly for barn eggs from the point of sales (POS) data on the basis of an investigation of 90 retail shops and examines the problems related to barn laying systems from farm on-site interviews. The POS data analysis uncovered the following points. The volume of AW eggs is about one percent of all shell egg POS sales. The investigation of retail shops showed that the number of AW egg items in the luxury supermarket or natural-foods supermarket is around 3-6 times more than that for ordinary food supermarkets. Thus, we concluded that barn egg prices should be standardized. From farm on-site interviews, we found that most poultry farm sell for organized consumers through co-op delivery system and home delivery business and that there are few poultry farmers who sell mainly on wholesale.
