Poultry farming

**Poultry Farming Methods:**
– Intensive Farming:
– Biomass of birds on Earth: 70% chicken and other poultry, 30% wild birds.
– World Watch Institute statistics: 74% of poultry meat, 68% of eggs produced intensively.
– Chicken Coop Controversy: Fresh air school vs. controlled-environment coop proponents.
– Egg-laying Chickens: Commercial hens lay eggs at 16-21 weeks, force-moulted for re-invigorated egg-laying.
– Alternative Farming:
– Free-Range Farming: Lower stocking densities, FDA-approved medications for disease prevention.
– Free-Run System: Hens roam freely in enclosed barns with provided enrichment.
– Organic Farming:
– Organic management requirements: Selection of livestock, nutrition, health care, and living conditions.
– Soil Association standards in the UK: Maximum stocking density, hen limits, beak-trimming practices.
– Yarding:
– Definition and distinction from free-range farming.
– Husbandry technique: Hens released daily, challenges with aggressive roosters.
– Battery Cage Farming:
– Majority housing method, transition to enriched housing, cage structure, and issues with battery cages.

**Poultry Housing Systems:**
– Battery Cages for Egg Production:
– Construction, water, and food provision, issues with limited space and welfare concerns.
– Furnished Cages for Laying Hens: Designed for natural behaviors, welfare advantages, and requirements.
– Higher Welfare Indoor Systems:
– More space, natural light, and foraging opportunities, slower growth rate, and the Better Chicken Commitment standard.
– Free-Range and Organic Broilers:
– Differences in growth rates, outdoor space requirements, and focus on natural breeds and welfare standards.

**Poultry Meat Production:**
– Indoor Broilers:
– Raised on litter in climate-controlled housing, reach slaughter weight at 5-9 weeks, and protection from predators.
– Intensively Farmed Broilers:
– Issues with fast growth leading to deformities, overcrowding, and mortality rates due to heart failure.
– Free-Range Broilers:
– Slower growth, outdoor space requirements, and benefits for leg and heart health.
– Organic Broilers:
– Raised similarly to free-range broilers, slower growth, larger outdoor space allowance, and focus on natural breeds.

**Poultry Farming Challenges:**
– Animal Welfare Concerns:
– Culling of male chicks, beak trimming, antibiotic usage, and arsenic in poultry feed.
– Health Concerns:
– E. coli contamination in chicken meat, avian influenza risks, and various bacterial strains affecting poultry health.
– Efficiency and Economic Factors:
– Soybean-based feeds, feed efficiency, economic pressures, commodity price changes, and waste management.

**Environmental and Health Impact:**
– Waste Management and Mortality:
– Poultry manure management, waste disposal methods, environmental concerns, and health risks for poultry workers.
– Disease Control:
– Avian influenza risks, bacteria strains affecting poultry, and challenges in disease prevention in poultry farms.
