A broiler chicken is a type of chicken specifically bred for meat production. These remarkable birds are the result of careful selective breeding, primarily from White Cornish and White Plymouth Rock crosses, creating highly efficient meat-producing breeds like the Cornish Cross.
Unlike laying hens that are slim and produce eggs, broilers are stockier birds that channel their energy into rapid muscle growth.
Modern broilers demonstrate extraordinary growth rates, reaching market weight of 5-6 pounds (2.3-2.7 kg) in just 6-7 weeks. This remarkable efficiency comes from genetics and specialized nutrition – no growth hormones are used or needed.
Both male and female broilers are raised for meat
Males typically grow slightly larger
A chick starts at ~40g and can reach over 2.5 kg in 6 weeks
Broilers require specific care to support their rapid growth:
High-protein feed (starter: 22-24%, grower: ~20%)
Constant access to fresh water
Temperature management (cooler as they grow)
Adequate space for movement
Regular health monitoring
Typically processed by 6-8 weeks
Key differences:
Body Type: Broilers are stocky with heavy breast muscle; layers are slim
Growth Rate: Broilers reach 5-6 lbs in 6-7 weeks; layers ~2 lbs
Purpose: Broilers for meat; layers for eggs
Lifespan: Broilers are processed young; layers live several years
Feed Needs: Broilers need higher protein; layers need more calcium
Activity: Broilers less active; layers more energetic
