Best Chicken Breeds for Meat Production

Not all chickens are built for the table. Choosing the right meat breed is the single most important production decision in poultry farming. Get it right and you have fast growth, good carcass quality, and a profitable operation. Get it wrong and you are feeding birds for twice as long to get half the meat.

This guide covers the best chicken breeds for meat production, from the industry-dominant Cornish Cross to heritage breeds preferred by pastured and organic producers, with an honest look at the trade-offs each involves.

What Makes a Good Meat Breed?

A chicken breed’s value for meat production comes down to five factors:

Factor	What It Means	Why It Matters
Feed Conversion Ratio (FCR)	Kg of feed to produce 1 kg of live weight	Lower FCR = lower feed cost per kg of meat
Days to Market Weight	Age at which bird reaches target slaughter weight	Faster = lower feed and labor cost
Carcass Yield	Percentage of live weight as dressed carcass	Higher yield = more meat per bird purchased
Breast Meat Proportion	Percentage of carcass as breast meat	Breast commands highest market price
Mortality Rate	Percentage of birds that die before slaughter	Lower is always better for profitability

Commercial Broiler Breeds

1. Cornish Cross (Broiler)

The Cornish Cross is the dominant commercial meat chicken worldwide. It is not a true breed but a hybrid cross, typically between a Cornish male and a White Plymouth Rock female. Virtually all chicken meat sold in supermarkets globally comes from this hybrid or close variations.

Performance:

Days to 2 kg live weight: 35 to 42 days
FCR: 1.7 to 2.0 (one of the best in any livestock species)
Carcass yield: 70 to 75 percent
Breast meat: Exceptionally high proportion

Advantages: Unmatched growth rate and feed efficiency. Low cost per kg of meat produced. Widely available as day-old chicks from hatcheries globally.

Disadvantages: Health problems are common. Fast growth puts stress on the heart, lungs, and legs. Birds require strict environmental management. They cannot breed naturally. They are poorly suited to outdoor and pasture systems because their leg strength often cannot support their fast-growing body.

Best for: Commercial indoor broiler operations with full environmental control. Not suitable for free-range or pasture production.

2. Ross 308 / Ross 708

Ross 308 is the most widely used commercial broiler strain globally. It is a proprietary strain developed by Aviagen for exceptional uniformity, rapid growth, and high breast meat yield. Ross 708 is a heavier-framed variant designed for large-bird production (whole bird and portioning markets).

Performance statistics are similar to the general Cornish Cross description above, with Ross 308 achieving slaughter weight at 35 days in controlled commercial environments.

Best for: Large-scale commercial broiler integrators with controlled environment housing and contracted growing arrangements.

3. Cobb 500

Cobb 500 is the other major global broiler strain, produced by Cobb-Vantress. It competes directly with Ross 308 for market share and performs comparably. Some markets favor Cobb 500 for its slightly better feed conversion in warm tropical climates, making it the more popular choice in Southeast Asia, Latin America, and Africa.

Best for: Commercial operations in warm and tropical climates.

Slower-Growing and Heritage Meat Breeds

Not every farmer wants to run a commercial broiler shed. For pastured poultry producers, organic farmers, and small-scale operations selling direct to consumers, slower-growing and heritage breeds often deliver better flavor, better welfare, and a premium price.

4. Freedom Ranger

The Freedom Ranger (and similar Label Rouge-type breeds) was developed specifically for outdoor and pasture systems. It grows slower than a Cornish Cross (reaching 2 to 2.5 kg at 9 to 11 weeks) but it is robust enough to range actively, producing darker meat with significantly better flavor.

Performance:

Days to market weight: 63 to 77 days
FCR: 2.0 to 2.5
Carcass yield: 68 to 72 percent

Advantages: Excellent foraging ability, good leg strength, superior flavor, better suited to free-range certification requirements, commands premium retail price.

Best for: Pastured poultry operations selling directly to restaurants, farmers markets, and premium consumers.

5. Delaware

The Delaware is a classic American dual-purpose breed with a respectable meat profile. Originally developed as an intermediate-speed commercial bird before the Cornish Cross took over, it produces a well-muscled carcass with good flavor in 10 to 12 weeks.

Best for: Small farms that want a multipurpose bird that produces both eggs and meat, and that fits into a slower, more natural production model.

6. Naked Neck Broiler Lines

In tropical regions, Naked Neck birds crossed with commercial broiler genetics produce heat-tolerant heavy birds that outperform standard broilers in hot climates. The naked neck trait reduces feathering by 40 percent and significantly lowers heat stress.

Best for: Commercial broiler production in very hot tropical climates where standard broiler mortality is high.

7. Sasso

Sasso is a French slow-growing breed group available in multiple lines for meat, dual-purpose, and pastured production. Sasso T451 and S451 lines have become popular in tropical markets including Africa and Southeast Asia for their heat tolerance, strong foraging ability, and acceptable growth rate.

Days to market weight: 70 to 90 days
FCR: 2.5 to 3.0
Popular in markets that value traditional taste over commodity production

Side-by-Side Breed Comparison

Breed	Days to Market	FCR	Best System	Flavor
Cornish Cross	35 to 42	1.7 to 2.0	Commercial indoor	Mild
Ross 308	35 to 38	1.75 to 1.95	Commercial indoor	Mild
Freedom Ranger	63 to 77	2.0 to 2.5	Pasture and free-range	Rich
Delaware	70 to 84	2.5 to 3.0	Small farm dual-purpose	Good
Sasso	70 to 90	2.5 to 3.0	Tropical semi-intensive	Rich
Naked Neck Broiler	50 to 60	2.0 to 2.3	Tropical commercial	Moderate

How to Choose the Right Breed for Your Farm

The right breed depends on your system, your market, and your climate. Use these questions as a guide:

Are you selling commodity meat at competitive prices or premium meat to direct customers? Commodity: Cornish Cross. Premium: Freedom Ranger, Sasso, Heritage.
Do you have climate-controlled indoor housing? Yes: Commercial broiler strains. No: Freedom Ranger, Sasso, Naked Neck crosses.
Are you in a hot tropical climate? Yes: Sasso, Naked Neck broiler lines, Cobb 500. Temperate: All options work.
Do you want a dual-purpose bird that also lays eggs? Consider Delaware, Rhode Island Red, or Australorp rather than dedicated meat breeds.

Model your expected profitability for different breeds using the Farm Profit and Loss Calculator and the Poultry Feed Calculator to see how FCR and days to market weight affect your total cost per kg of meat produced.

Feed Management for Meat Birds

Meat bird feeding follows a standard 2-phase or 3-phase program:

Starter (days 1 to 14): 22 to 24 percent protein, formulated for fast early growth
Grower (days 15 to 28): 20 to 22 percent protein
Finisher (days 29 to slaughter): 18 to 20 percent protein, often medicated-free for the final 7 days

Broiler feed is almost always offered ad libitum (free choice) because restricting feed access directly reduces growth rate and increases time and cost to market weight.

Track flock performance and mortality using the Poultry Mortality Rate Calculator to benchmark against industry standards and catch health problems early.

Frequently Asked Questions

What is the fastest growing chicken breed for meat?

The Cornish Cross hybrid reaches 2 to 2.5 kg in just 35 to 42 days under optimal conditions, making it the fastest growing chicken breed available.

What is feed conversion ratio (FCR) and why does it matter?

FCR is the kg of feed needed to produce 1 kg of live weight gain. A lower FCR means more efficient feed use. Commercial broilers achieve FCR of 1.7 to 2.0, which is exceptional among livestock.

Are heritage meat breeds profitable?

Heritage breeds can be very profitable when sold direct-to-consumer at premium prices. They are rarely competitive at commodity market prices due to their slower growth and higher feed cost per kg.

What is the best broiler breed for hot climates?

Cobb 500 and Naked Neck broiler lines are the top choices for very hot climates. Both have heat tolerance advantages over standard Cornish Cross strains.

Can I raise meat chickens on pasture?

Yes, but use a breed designed for it. Freedom Ranger and Sasso birds are active foragers that thrive on pasture. Cornish Cross birds have leg and cardiovascular limitations that make outdoor ranging problematic.
