Global egg prices have surged due to avian influenza outbreaks and increased energy and feed costs. New Zealand has seen a shortage of 300,000 hens due to a law banning hen cages, leading to a rise in backyard chicken farming. This has resulted in concerns about the long-term egg supply and calls for mindful purchasing. Retailers have imposed purchase limits on eggs, and cafes have had to adjust their menus. The situation is severe in the US, Japan, and Malaysia, with significant bird culls and record-high wholesale egg prices.
