Costco's $4.99 rotisserie chickens have been a popular item, with various outlets exploring the secrets behind their low price and taste. However, some reports suggest that the chickens may be facing a problem, potentially even disappearance, although the nature of the issue is unclear. A class-action lawsuit has also been filed against Costco's rotisserie chickens, with one report mentioning a possible issue related to seaweed, but the details and outcome are uncertain.
