Broiler Chicken Welfare and Stocking Density Standards in the UK

UK broiler chicken welfare regulations set a maximum stocking density of 33kg/m2 rising to 42kg/m2 under enhanced conditions. Better Chicken Commitment signatories commit to lower densities of 30kg/m2 with superior breed requirements.

Key Facts

UK broiler regulations allow up to 33kg per m2, rising to 42kg/m2 under enhanced conditions
At 42kg/m2, each bird has roughly the space of an A4 sheet of paper
The Better Chicken Commitment (BCC) requires 30kg/m2 maximum stocking density
RSPCA Assured requires 30kg/m2 and a slower-growing breed
Higher stocking densities are associated with increased lameness, dirty litter, and foot pad dermatitis

Welfare Considerations

At the highest legal stocking densities, broilers in the final week before slaughter have minimal ability to move freely, access feeders and drinkers, or establish social interactions. Litter quality deteriorates rapidly at high densities due to moisture accumulation, causing foot pad dermatitis that is painful and associated with lameness. Lower density systems with better litter quality and slower-growing breeds represent a significantly better welfare outcome.

What You Can Do

Choose RSPCA Assured or BCC-committed chicken products
Ask your supermarket, restaurant, or employer catering about their stocking density commitment
Support Compassion in World Farming Better Chicken Commitment campaign
Contact fast food companies that have not signed the BCC to request commitment
Reduce chicken consumption and prioritise welfare-certified products when you do buy
