Cage-free vs free-range vs pasture-raised eggs: what is the difference?

Cage-free hens live loose inside a barn, free-range hens live in a barn with access to the outdoors, and pasture-raised hens spend part of every day on pasture with far more room outside. Cage-free and free-range are USDA definitions for eggs sold in USDA grade-marked cartons. Pasture-raised is not a USDA term: its meaning comes from private certification standards.

All three show up in USDA's wholesale price reporting, but only cage-free trades often enough to be priced almost every business day, which is why this site tracks a cage-free premium and no pasture-raised one. For cage-free against conventional caged eggs, see why cage-free eggs cost more.

What each label means

Cage-free. USDA's shell egg grading rules say eggs in a USDA grade-marked carton labeled cage-free are laid by hens "able to roam vertically and horizontally in indoor houses" with fresh food and water, in houses that include enrichments such as scratch areas, perches and nests (AMS grading procedure QAD 709, as amended April 22, 2025). Indoors is the operative word: the definition requires no outdoor access. It is also the floor for every egg sold in California, see California egg prices.

Free-range. The same indoor standard plus "continuous access to outdoors during their laying cycle", where the outdoor area "may be fenced and/or covered with netting-like material" (same USDA procedure). The USDA definition names no minimum outdoor area per hen. Private seals add numbers: Certified Humane's free-range standard, for example, sets 2 square feet of outdoor space per bird and at least 6 hours outside a day, weather permitting.

Pasture-raised. USDA has no definition, and its grading procedure says so directly: "Due to a lack of a single definition for pasture raised laying hens," eggs in a USDA grade-marked carton labeled pastured or pasture-raised must be certified by "a nationally recognized certifying body such as American Humane or Certified Humane." Under Certified Humane's standard (Humane Farm Animal Care, Egg Laying Hens), pasture-raised hens get at least 2.5 acres per 1,000 birds, which works out to 108 square feet each, on pasture that must be rotated, and they must be outside every day of the year for at least 6 hours.

USDA's grading rules do treat the three as a ladder, in one direction only. A certified pasture-raised egg may be packed into a free-range or cage-free carton, and a free-range egg into a cage-free carton, but never the reverse (QAD 709.14b). Every pasture-raised egg in a USDA-graded carton therefore also qualifies as free-range and cage-free.

Where each label shows up in USDA's price data

USDA's Daily National Shell Egg Index sorts negotiated wholesale trades by production system, and caged, cage-free, free-range, organic and pasture-raised eggs each have their own lines. What differs is how often each one prints: USDA publishes a line only on days when enough trades are confirmed. In the 12 months to September 22, 2026, in this site's copy of that feed:

• Conventional (caged) large white, loose: priced on 251 days
• Cage-free large white, loose: 217 days
• Free-range large brown, loose: 18 days, all within three months, the last on January 30, 2026
• Organic large brown, loose: 14 days, the last on May 15, 2026
• Pasture-raised large brown, loose: 14 days, all within three months, the last on July 7, 2026

A line that prints 14 days a year is not a benchmark, and the pasture-raised prices that did post swung from 70 cents a dozen in March 2026 to 31 cents in July: single lots, not a market. Yet those eggs sell in volume at retail (see the ad counts below), so a tier that fills store shelves but barely registers in the index is reaching stores some other way than trade-by-trade negotiation. Cage-free has enough buyers and sellers dealing in the open to clear a price nearly every day, and that depth has a size behind it: USDA estimated the cage-free flock at 150.7 million hens in August 2026 (AMS Monthly Cage-Free Shell Egg Report), which works out to about 47% of the 317.3 million table-egg layers NASS counted that month.

That chart is the thing a pasture-raised tier cannot have: a premium needs two prices on the same day, every day. Cage-free has them, so its premium over conventional is a live number, -14.5¢/doz premium on USDA's index as of the latest print.

What shoppers see: the ladder in grocery ads

The retail side has no gaps. USDA's weekly report on grocery store egg ads tracks every tier every week, with the average advertised price and the number of stores running the ad. Across the nine weekly reports from July 20 to September 14, 2026, a dozen large eggs averaged, weighted by the stores advertising them:

• Conventional white: $1.28
• Cage-free white: $2.23
• Cage-free brown: $3.00
• Free-range brown: $4.55
• Organic brown: $5.07
• Pasture-raised brown: $6.06
• Organic pasture-raised brown: $7.55

Worked example. Compare brown with brown, since every pasture-raised line in USDA's national ad and wholesale data is a brown egg: pasture-raised at $6.06 against cage-free at $3.00 is $3.06 more a dozen, about 25 cents an egg, roughly double. Now set that beside wholesale. Over the same weeks the national cage-free premium on USDA's index averaged 2.1 cents a dozen (it ranged from 22.4 cents below conventional to 29.8 above), while the ad gap between cage-free white and conventional white was 95 cents. The shelf spreads between tiers are far wider than anything the wholesale market prices, and above cage-free there is barely an open wholesale market to price them at all.

These are advertised prices, the specials in weekly grocery ads, not the average shelf price, and they swing week to week. Pasture-raised brown ran in more store listings than any other tier listed here, 19,871 against 17,856 for free-range brown and 3,399 for conventional white. What retail feature activity means explains how to read those counts.
