A bird flu outbreak has led to the culling of 1.4 million laying hens, resulting in a shortage of 1 million eggs per day in the Polish market. Poultry farmers are still required to deliver these non-existents eggs to retail chains at previous prices, causing financial strain. The National Federation of Poultry Breeders and Egg Producers has expressed concerns about the retail chains' pricing policy potentially leading to a collapse in deliveries and market instability before Christmas. The industry is calling for a reasonable approach to egg purchase pricing to prevent further market destabilization.
