The article highlights the difference in the impact of the avian flu outbreak, which has led to the slaughter of millions of laying hens in the US, on the egg market in Spain and the US. The US is experiencing an egg shortage and significant price hikes, with the average price of a dozen eggs reaching over three times the price from a year ago, while Spain is not as affected due to a solid internal market that makes it less dependent on external events. The US is trying to offset the shortage by importing eggs from cheaper sources and considering alternatives to eggs in food manufacturing. The article also notes the decline in caged egg production in Spain and the EU's focus on the intra-community market.
