Who makes it

Supplier companies

6 companies produce commercial layer hen genetics (day-old chicks / pullets).

Hendrix Genetics

HQ NL50% share

PE-backed (Paine Schwartz Partners) Dutch genetics company. Holds leading genetic positions across 6 separate protein supply chains: pigs (Hendrix Genetics Swine / Hypor + Danish Genetics, merged Jan 2025), turkeys (Hybrid Turkeys), laying hens (ISA), Atlantic salmon (Landcatch), trout (Troutlodge), shrimp (Kona Bay). 3,400+ employees, 100+ countries.

EW Group GmbH

HQ DE45% share

EW Group GmbH (Visbek, Lower Saxony, Germany; private, family-owned by the Wesjohann family; founded 1932 as an egg-trading business; estimated annual revenue €3B+ across all divisions) is the parent company of Hy-Line International (the world's #1 layer genetics company by chick volume) and Lohmann Tierzucht GmbH (dominant in Europe and Asia). EW Group is a closely held German family business — the Wesjohann family simultaneously controls PHW-Gruppe, Germany's largest poultry meat company (including Wiesenhof chicken), making EW Group a uniquely integrated genetics-to-meat conglomerate. Through Hy-Line and Lohmann together, EW Group controls approximately 45% of world commercial layer genetics. EW Group also owns Aviagen (broiler genetics) — a Scottish company that breeds Ross and Arbor Acres broiler lines (dominant in global broiler meat production) — meaning a single German family controls the dominant genetics for BOTH the world's egg supply (through Hy-Line + Lohmann) AND a large share of the world's chicken meat supply (through Aviagen). This dual-market position makes EW Group the most consequential private family business in global food production that most people have never heard of.

Hy-Line International

HQ US30% share

Hy-Line International (Iowa City, Iowa; wholly owned subsidiary of EW Group GmbH, Germany; founded 1936 by Henry A. Wallace — the US Secretary of Agriculture under FDR and 33rd US Vice President — as a hybrid corn and poultry breeding venture; now the world's #1 layer genetics company by commercial chick volume) produces the Hy-Line Brown (dominant in US, Latin America, and India), Hy-Line W-36 (dominant US white egg breed), and Hy-Line W-80 (ultrawhite egg, specialty market). Hy-Line maintains great-grandparent (GGP) flocks at its primary US breeding facility in Iowa City, Iowa. Hy-Line's W-36 white leghorn breed is the standard commercial layer in US cage operations and historically has been the workhorse of the US egg industry. Hy-Line was acquired by EW Group in 2000. Hy-Line supplies grandparent stock to multiplier hatcheries in 100+ countries and has technical service teams on every continent. During the 2022-2024 HPAI outbreak, Hy-Line's Iowa breeding operations were a critical chokepoint — any HPAI breach of GGP flocks at Iowa City would have required sourcing replacement GGP stock from international backup facilities, potentially adding 12-18 months to US flock repopulation timelines.

Cal-Maine Foods(CALM)

HQ US20% share

Largest producer and distributor of fresh shell eggs in the United States, producing approximately 20% of all commercially produced US eggs (~13 billion eggs/year). Revenue $4.26B in fiscal year ending May 2025 (83% growth driven by H5N1-related price surge). Total flock ~40+ million hens.

Lohmann Tierzucht GmbH

HQ DE20% share

Lohmann Tierzucht GmbH (Cuxhaven, Lower Saxony, Germany; wholly owned subsidiary of EW Group GmbH; founded 1959; formerly part of BASF Animal Nutrition division before EW Group acquisition) produces the Lohmann Brown-Classic — the dominant layer breed in Europe, Southeast Asia, and the Middle East — and the Lohmann LSL-Classic (white egg, dominant in Germany, Netherlands, and Scandinavia). The Lohmann Brown-Classic produces 300-330 eggs per year under commercial conditions, with excellent livability and adaptive performance in cage-free environments — making it the preferred breed as EU cage-free transition mandates take effect. Lohmann maintains GGP flocks in Cuxhaven (Germany) and internationally. Lohmann is the market leader in Germany (naturally — the home of EW Group) and holds strong positions across Europe, Turkey, India, and Southeast Asia. Lohmann's Cuxhaven headquarters and breeding facilities represent a second critical node in EW Group's GGP infrastructure, alongside Hy-Line's Iowa City facility.

Aviagen Group

HQ GB2% share

Aviagen Group (Huntlywood, Midlothian, Scotland; wholly owned subsidiary of EW Group GmbH, Germany; formed by EW Group in 2002 from merger of Ross Breeders and Arbor Acres) is the world's largest broiler (chicken meat) genetics company — producing the Ross 308 and Ross 708 broiler breeds that together dominate global broiler production. Aviagen is noted here primarily because it is a co-subsidiary of EW Group alongside Hy-Line and Lohmann — meaning the same German family (Wesjohann/EW Group) controls dominant genetics for eggs (Hy-Line + Lohmann), chicken meat (Aviagen Ross), and turkey (British United Turkeys). Aviagen has limited layer operations (through its Lohmann sister company under EW Group). The combined EW Group poultry genetics portfolio — Hy-Line layers + Lohmann layers + Aviagen broilers — constitutes the most concentrated position in global food supply genetics in existence. No government has subjected EW Group's dual egg-and-meat genetics dominance to antitrust scrutiny.
