Chicken Egg Production (United States) — NAICS 11231

An investor's primer. The North American Industry Classification System (NAICS) 2022 code 11231 is a NAICS industry (5-digit level) covering U.S. farms whose main business is raising chickens to lay eggs. It contains a single child industry — 112310 — so this level and that child are effectively the same thing. Written for both public-market and private investors. This is a short rollup page; for full detail see the 112310 primer.

1. Overview

Chicken egg production is a large, low-margin, biologically driven commodity food business, with a growing branded and value-added layer on top. The core assets are laying flocks, barns and feed systems, egg collection, grading and packing, cold-chain logistics, processing plants, and customer relationships. The economics are a classic boom-bust commodity cycle: supply swings on feed-grain costs (corn and soybean meal) and on highly pathogenic avian influenza (HPAI, or "bird flu"), so egg prices can spike and collapse within a single year.

Because NAICS 11231 has exactly one child industry, everything in the full 112310 primer applies here without change — this page summarizes the level and its own headline figures, then points to 112310 for depth.

2. What's inside — and why this level equals its one child

NAICS organizes the economy into nested levels: sector (2-digit) → subsector (3-digit) → industry group (4-digit) → NAICS industry (5-digit) → national industry (6-digit). At most levels a 5-digit industry splits into several 6-digit children. Chicken egg production does not: the U.S. Census Bureau assigns 112310 — Chicken Egg Production as the sole national industry inside 11231 [4]. The two codes therefore describe the same set of farms — those primarily engaged in raising chickens to produce table (food) eggs and hatching eggs [4].

This is a "pass-through" level: there is nothing in 11231 that is not also in 112310, and no sibling industries to compare against. Adjacent egg-related activities sit in different codes — meat-type (broiler) chickens in 112320, poultry hatcheries in 112340, and the breaking of shell eggs into liquid, frozen, or dried egg products in food manufacturing (chiefly NAICS 311999) — none of which roll up into 11231 [4].

3. Size (this level's rollup figures)

We have no ingested official stat_metrics for NAICS 11231 in our ground-truth reference file — that file is empty for this node — so the figures below are drawn from the cited federal and company sources used in the 112310 primer, labeled accordingly. Because 11231 equals 112310, the child's numbers are this level's numbers.

  • Value of production. The value of all U.S. egg production reached $21.0 billion in 2024, up 18% from $17.9 billion in 2023, ranking eggs the 8th-largest source of cash receipts among U.S. farm commodities [1].
  • Physical output (USDA NASS, 2025). Average laying hens ~365 million; eggs per layer 288; ~105 billion total eggs (about 90.1 billion table eggs and 15.2 billion hatching eggs) [2]. The flock fell from roughly 375 million in 2024 as HPAI culls cut supply.
  • Small-business threshold. The U.S. Small Business Administration (SBA) size standard for this industry is $19.0 million in average annual receipts — a federal classification ceiling for contracting and lending, not a measure of industry size [3].

Undercount caveat (important). Standard Census Bureau business statistics (firm counts, employment, payroll, receipts from the Economic Census / County Business Patterns) are not the authoritative yardstick here: County Business Patterns explicitly excludes crop and animal production (all of NAICS 11), plus nonemployer and self-employed farm businesses. The coverage gap is small farms and nonemployer farm activity — not government ownership. For this industry, farm-level USDA data (above) are the right measure, and we do not estimate a Census-style market size. These are production and value figures — do not add them to public-company sales or treat them as a NAICS revenue total.

4. Investable universe (where value concentrates)

With a single child industry, there is no cross-child allocation to make — value concentrates by company type, not by sub-industry. Public pure-plays are scarce; most of the industry is privately held.

  • Public pure-plays (two). Cal-Maine Foods (CALM, Nasdaq) — the largest U.S. shell-egg producer and the most direct bet on the commodity cycle and consolidation; and Vital Farms (VITL, Nasdaq) — a branded, pasture-raised specialty grower, analyzed as a consumer-staples story rather than a commodity producer [8][9].
  • Indirect public exposure. Post Holdings (POST, NYSE) via Michael Foods, the largest U.S. egg-products processor [12]; and JBS (JBS, NYSE) through its Mantiqueira USA joint venture (JV), which acquired Hickman's Egg Ranch in 2025 [13].
  • Private majors (where most output sits). Rose Acre Farms (~25 million hens), Versova, Daybreak Foods (~23 million), and Hillandale Farms (bought by Brazil's Global Eggs for ~$1.1 billion in 2025) [11][14]. A USDA snapshot put the five largest producers at 32.2% of U.S. egg production [6].

See the 112310 primer, Section 4, for the full company-by-company table and scale figures.

5. How the money works

Egg producers are commodity manufacturers of a perishable food — no regulated-utility rate base, no real-estate funds-from-operations, no mining all-in sustaining cost applies. The one-line model: dozens sold × realized price per dozen + processed products − production, packing, distribution, and overhead cost.

  • Feed is the swing input — roughly two-thirds corn and one-fifth soybean meal by weight, and the single largest cost. Cal-Maine's FY2025 filing put feed at $0.490 per dozen (53.4% of a $0.918 total farm production cost) [8].
  • Price is a commodity spot market, making producers price-takers. The FY2025 bird-flu spike shows the extreme: Cal-Maine's average selling price jumped to $3.134/dozen from $1.932, and net income to $1.22 billion from $277.9 million — a shortage peak, not a sustainable margin [8].
  • Two profit models: low-cost commodity scale (Cal-Maine, Rose Acre) versus branded / asset-light premium (Vital Farms, targeting $2 billion revenue by 2030 at 15–17% adjusted EBITDA margins) [10]. Government indemnities for USDA-ordered flock culls add real cash inflows during outbreaks [22].

Full detail — the three product layers (conventional, specialty, processed) and the unit economics investors track — is in the 112310 primer, Section 5.

6. Demand drivers

Eggs are a dietary staple with slowly growing, relatively inelastic demand, reinforced by protein/nutrition marketing and broad foodservice and food-manufacturing use (liquid and dried egg in mayonnaise, baked goods, prepared meals) [7][20]. The main growth lever is premiumization — a durable shift toward cage-free, organic, and pasture-raised eggs driven by both consumer preference and law. At extreme prices consumers cut back or switch proteins, visible in the 2025 per-capita consumption dip [7][8].

7. Regulation

Eggs sit under an unusually split federal structure plus a fast-moving patchwork of state welfare laws:

  • FDA Egg Safety Final Rule — Salmonella Enteritidis prevention at producers with 3,000+ hens [19].
  • USDA AMS — voluntary shell-egg grading and handler surveillance [21]; USDA FSIS — continuous inspection of egg products under the Egg Products Inspection Act of 1970 [20]; USDA APHIS — HPAI response, depopulation, and indemnity [22].
  • EPA — CAFO (concentrated animal feeding operation) permitting and nutrient management for large operations [25].
  • State cage-free / welfare laws — the fastest-moving force. California's Proposition 12 and Massachusetts' Question 3 require in-state-sold eggs to be cage-free; Cal-Maine reported ten states with such rules. Roughly 35% of the U.S. flock is now cage-free and rising, lifting average prices but front-loading capital cost [23][24].

8. Consolidation

The industry is concentrated at the top and fragmented below. Cal-Maine reported the ten largest producers owned about 54% of U.S. table-egg layer hens at year-end 2024 [8], and the biggest players keep buying the rest (Cal-Maine's ISE America and Echo Lake Foods deals; Global Eggs' $1.1 billion Hillandale purchase; Mantiqueira/JBS's Hickman's acquisition) [13][14][24]. Foreign and family capital is now entering U.S. egg assets. Antitrust is a live overhang: in 2026 the U.S. Department of Justice (DOJ) and 17 states filed a civil case and proposed settlements involving Cal-Maine, Versova, and Hickman's over alleged benchmark coordination (no admission of wrongdoing) [21].

9. Risks

  • HPAI (bird flu) — the dominant risk. Over 30 million U.S. laying hens were lost in 2025; outbreaks destroy flocks overnight and rebuilding takes months [22].
  • Commodity price whiplash. Retail eggs hit ~$6.22/dozen in March 2025 and can halve within weeks; earnings are extremely volatile [23].
  • Feed-cost inflation, customer concentration (Cal-Maine's top three customers were 49.2% of FY2025 sales) [8], cage-free over-investment, food-safety recalls, environmental opposition, and antitrust/political scrutiny [19][25][21].
  • Concentration risk for public investors. With only two pure-plays, a single-company event moves the entire thin public opportunity set.

10. How to invest & outlook

Because 11231 is a single-child level, the investment routes are identical to 112310's. Public: Cal-Maine (CALM) for the commodity cycle; Vital Farms (VITL) for premium-brand growth; Post (POST) and JBS (JBS) for indirect exposure — and avoid valuing a producer on one shortage-inflated year [8][9][12][13]. Private (most of the industry): direct or private-equity stakes in large private producers, plus farms, packing plants, egg-processing assets, asset-backed lending, and farmland/barn/feed-mill/cold-chain real assets; diligence flock ownership, disease history, indemnity assumptions, feed procurement, housing compliance, and customer contracts.

Outlook. USDA's Economic Research Service (ERS) expects production to rise in 2026 and prices to normalize sharply lower off the 2025 spike (retail down ~30%, farm-level much more), with wide prediction intervals [25]. The reasonable base case is a structurally flat-volume, premiumizing industry whose reported results stay violently cyclical around bird-flu shocks — investors choose between riding the cycle at the lowest-cost scale producer or stepping up to a branded growth story.
