Broiler Parent Flock Welfare and Feed Restriction

Broiler breeder birds (parent flocks) are genetically selected for fast growth but must be kept underweight to maintain fertility. This requires severe feed restriction that causes chronic hunger.

Key Facts

Broiler breeders are feed-restricted to 25-50% of ad libitum intake to prevent obesity and maintain fertility
Unrestricted broiler breeders would grow to weights causing cardiac and leg problems
Feed-restricted birds show persistent foraging motivation, oral stereotypies and aggressive feeding competition
The feed restriction period lasts throughout the productive life of the breeder flock
Females and males are typically segregated and fed differently due to different requirements
Some companies have begun developing slower-growing breeder strains that require less restriction
The welfare cost of parent flock restriction is estimated to affect tens of millions of birds globally

Welfare Considerations

Broiler breeder welfare represents a profound ethical tension: the birds that produce the eggs for meat chicken production are themselves chronically hungry by design. They have inherited the fast-growth genetics that make unrestricted feeding dangerous, but must be kept well below satisfying intake throughout their lives. The hunger motivation is persistent and measurable - breeder hens will work harder than any other study species to access additional food. This is not an obscure detail of industrial farming; it is a systematic welfare failure affecting the foundation of the broiler industry.

What You Can Do

Support the Better Chicken Commitment which addresses parent flock welfare alongside broiler welfare
Choose slow-growth chicken from producers who source from welfare-certified parent flocks
Advocate for parent flock welfare standards to be included in poultry welfare legislation
Support research into slow-growth genetics that reduce the need for feed restriction in breeders
Reduce broiler chicken consumption to reduce demand pressure on parent flock production
