FAT Research Series — Economic Concentration
How firm concentration and integrator control combine to shape competition, grower dependence, and retail disclosure in the most vertically coordinated of U.S. protein systems.
Executive Summary
Broiler chicken is the most vertically coordinated of the major terrestrial animal-protein systems in the United States. USDA’s 2023 meat-processing concentration paper reports a broiler CR4 of about 52% based on 2021 FSIS data. On paper, that national share may appear somewhat lower than beef. In practice, however, the chicken industry is often more dependent on integrator control because firms coordinate feed, chicks, veterinary protocols, grow-out contracts, transportation, and processing in one system.
Measures of Concentration in Chicken
For broilers, concentration analysis should combine firm concentration with vertical coordination. Older ERS work on poultry and broilers remains important because it explains why production contracts and vertical integration became the dominant organizing logic of the industry. As a result, a national CR4 can understate the lived dependence of growers whose practical market may be a single integrator and plant complex.
| Measure | Why it matters | Chicken-specific concern |
|---|---|---|
| CR4 | Top-four national share | Useful but incomplete |
| HHI | Merger screen | Can miss local monopsony conditions |
| Integrator control | Ownership or control of key inputs | Central to grower dependence |
| Regional plant dependence | Number of realistic buyer options nearby | Often one complex dominates |
Broiler Structure: Integration More Than Spot Markets
ERS’s classic work on pork and broiler coordination describes how production contracts and vertical integration in broilers facilitated technology adoption, quality control, and assured market outlets. Those efficiencies came with concentrated control. Claire Kelloway’s Food & Power reporting on chicken and livestock concentration helps frame the modern consequence: growers may be nominally independent while operating within a system whose terms are largely set by the integrator.
FAT’s broiler supply-chain page is valuable because it moves the discussion from abstraction to visibility. Integrators, hatcheries, feed systems, processing plants, and brand identities can be treated as parts of one governed chain rather than as separate market actors. That makes economic concentration directly relevant to label disclosure. If the same integrator controls most material decisions, the consumer is typically seeing a curated set of claims rather than a full picture of ownership and production conditions.
Why Concentration in Chicken Is Not Only About CR4
An industry can be moderately concentrated on a national CR4 basis and still function as highly concentrated from the perspective of a contract grower or nearby community. USDA’s concentration studies, DOJ/FTC screening tools, and Kelloway’s reporting point in the same direction: local and functional concentration matters. In broilers, that means the relevant competition question may be less “How many firms exist nationally?” and more “How many realistic alternatives does a grower or region have?”
For FAT, the added point is that high integrator control can reduce information pluralism. Production methods, antibiotic practices, breed decisions, welfare protocols, and plant identity may all be standardized internally and disclosed selectively at retail. Consumers receive a simplified story from a deeply managed system.
Conclusion
Chicken concentration should be evaluated through both antitrust and disclosure lenses. CR4 and HHI remain useful, but they do not by themselves capture the power embedded in vertical integration and local plant dependence. FAT’s chicken work therefore treats economic concentration as a core disclosure category: the structure of the system influences the truth available to consumers at the shelf.
Sources and Methods
FAT uses a mixed-method approach. These papers rely on USDA Economic Research Service and Agricultural Marketing Service publications, DOJ/FTC antitrust guidance, Claire Kelloway’s Food & Power reporting, and FAT’s own supply-chain mapping pages. Concentration is evaluated with four complementary tools: (1) CR4, the share held by the four largest firms; (2) HHI, the standard DOJ/FTC concentration screen; (3) regional concentration, because local procurement and processing options often matter more than national averages; and (4) vertical coordination/integration, including contracts, formula pricing, and integrator control over inputs and processing. FAT treats these metrics as descriptive indicators, not as stand-alone proof of unlawful conduct.
