Poultry Farming: The Chicken and the Egg
Imagine a world where billions of birds are raised each year for meat or eggs. That’s exactly what poultry farming is all about, involving domesticated birds like chickens, ducks, turkeys, and geese. But how much do we really know about this industry? Is it as simple as it seems?
The Numbers Game
More than 60 billion chickens are killed annually worldwide. That’s a staggering number! Among these, some are raised for eggs (layers) and others for meat (broilers). The FDA oversees poultry production in the US, while DEFRA regulates it in the UK. But what about the rest of the world? How do they manage their poultry farms?
Intensive vs Free-Range Farming
74% of the world’s poultry meat is produced intensively, with alternative methods like free-range farming using lower stocking densities. Intensive farming involves raising birds in confined spaces, while free-range allows them to roam freely during the day. But which method truly benefits the chickens?
The Chicken Coop Conundrum
Chicken coops vary widely in design. Some advocate for ventilation and open spaces, believing that controlled environments are necessary. Egg-laying chickens typically begin laying eggs at 16-21 weeks of age, with production declining after 25 weeks. Commercial breeds can produce over 300 eggs a year.
Free-Range Farming: A Natural Choice?
Free-range poultry farming allows chickens to roam freely during the day but often confines them at night or in bad weather. The UK and EU regulate free-range egg farming, requiring hens to have access to open-air runs and minimum stocking rates. Suitable land requires adequate drainage, protection from prevailing winds, good ventilation, access, and predator protection.
Benefits of Free-Range Farming
Free-range farming benefits include natural behaviors for hens and opportunities for natural behaviors like pecking, scratching, foraging, and exercise outdoors. However, both intensive free-range poultry and ‘cage-free’ farming have animal welfare concerns, including cannibalism, feather pecking, vent pecking, diseases, and predators.
Beyond the Coop: Broilers and Beyond
Broilers are raised indoors on litter in climate-controlled housing, reaching slaughter weight at 5-9 weeks of age. The floor is covered with bedding material to maintain flock health, and most houses have enclosed watering systems to reduce spillage. Some houses feature curtain walls or tunnel ventilation to admit natural light and fresh air.
Challenges in Broiler Farming
Intensive broiler sheds can become highly polluted with ammonia from droppings, requiring additional fans to bring in fresh air. If not properly managed, broilers can suffer from various health issues including eye damage, respiratory problems, leg burns, and heart failure due to overcrowding and stress.
Free-Range Broilers: A Step Forward?
In contrast, free-range broilers are reared under similar conditions as free-range egg-laying hens, offering opportunities for natural behaviors like pecking and scratching. Organic broiler chickens have more space allowance outside (at least 2 square meters per bird) and slower growth rates due to restrictions on in-feed or in-water medications.
Dual-Purpose Chickens: A New Breed?
The concept of dual-purpose chickens, which can be used for both eggs and meat production, has emerged as a possible solution. The Demeter network in Germany supports this approach. In Switzerland, two million chicks are killed almost at birth, but some are sold to zoos or animal stores, while others are transformed into biogas.
Beak Trimming: A Controversial Practice
Beak trimming is a routine practice in the poultry industry. However, it has been shown to cause pain and chronic pain in birds. Animal welfare groups have criticized these practices, and some advocate for more humane methods such as low atmospheric pressure stunning or inert gas asphyxiation.
The Future of Poultry Farming
As the world chicken population continues to grow, so do concerns about animal welfare. The poultry industry is facing criticism over its treatment of animals, and solutions are being explored to improve conditions. The German company Lohmann has integrated this concept on a large scale, producing dual-purpose chickens that can be used for both eggs and meat.
Conclusion
The journey from the coop to the plate is complex and fraught with challenges. As consumers, we must ask ourselves: Are the practices in place truly humane? The answers may not be straightforward, but one thing is clear—there’s a need for continuous improvement in the poultry industry.
