Heatwave cuts French egg output and size, tightening supply
Executive summary: A June heatwave led to the death of up to 2% of laying hens in France and decreased egg production, resulting in fewer and smaller eggs. Lower egg supply and reduced egg size can raise retail prices and increase costs for food manufacturers that rely on standard egg specifications.
Who is involved: French poultry producers, egg distributors, retailers, and EU agricultural regulators are the primary actors.
Likely next: If high temperatures persist, producers may accelerate cooling investments and feed adjustments to limit further losses.
A June heatwave caused up to 2% mortality in laying hen flocks across France, while also reducing lay rates and yielding smaller eggs. The combined effect lowers egg availability and shifts the size distribution, which can affect both retail prices and processed food formulations. Poultry farmers face higher replacement costs and may need to invest in cooling or ventilation to mitigate future losses. Market participants are watching for any policy response to animal welfare concerns during extreme weather.
