Impact of Heat Wave on Poultry Farming in France

During a severe heat wave in June, poultry farmers in France faced devastating losses. Chickens, particularly susceptible to heat, suffered significantly. On June 23, in one of the hottest periods on record for the region, temperatures soared inside a shed at a farm in Laubrières, leading to the death of 1,500 chickens within a few hours. Isabelle Renaudier, a farmer raising chickens for various markets, discovered that one-third of her flock had perished. Renaudier expressed heartbreak over the loss.

Chickens are highly vulnerable to heat due to their inability to sweat and their feather-covered bodies. When exposed to extreme temperatures, they pant to cool down, risking dehydration and energy depletion. Slow-growing outdoor chickens, like those managed by the Renaudiers, are also at risk. However, broiler chickens raised by large-scale industries face an additional challenge. These chickens, designed to grow rapidly within five weeks, have a fast metabolism that makes them naturally warmer. Consequently, despite their suitability for meat production, they struggle to survive in rising global temperatures.

Sylvia Goisbault, another farmer in northwestern France, also experienced changes due to the heat. Although her farm provides wheat to feed the chickens, she plans to alter her farming schedule to avoid having slaughter-ready birds during the summer months.

This incident highlights the broader issues facing agriculture in a warming world. Adaptations in farming practices are crucial to mitigate losses and ensure the health and welfare of livestock.
