Prices for organic eggs held steady at an average of $2.34/dozen from July 2004 through June 2006, with a constant range of $2.17 to $2.50.

Organic price data for eggs and poultry at the intermediary level became available in USDA AMS’s Market News Reports starting in January 2004. Only prices for brown eggs are currently reported by AMS since the majority of the organic egg market comprises brown eggs.
