Eggs can come with a lot of labels these days — free-range, organic, cage-free. How is a consumer to know which ones are the best choice? As explained in 30 Days to a Greener You, you’ll get detailed information on where your egg came from if you input the producer and grader codes into this website. Or you could check out our handy guide so you know what the words on the packaging mean for the next time you’re grocery shopping.
Here’s the breakdown of what all those labels on your eggs mean.
1. Conventional eggs: These eggs often don’t have their harvesting practices labelled, and are usually the least expensive. In conventional systems, four hens are typically housed in each two-square-foot battery cage, in barns containing thousands of birds. This makes them prone to injury and infection, so they receive antibiotics daily, as well as hormones to increase egg production. Their feed is unregulated, so they’re often fed leftover animal by-products mixed with grain. Battery cages are banned in the EU and are often the subject of animal-rights debates.
2. Free-run eggs: Free-run hens are not confined to life in a cage, but are allowed to roam the floor of the barn. They are still densely packed into these barns with no required outdoor access. Free-run hens eat the same feed as conventionally raised hens, and are given antibiotics and hormones.
3. Free-range eggs: Free-range hens must have access to the outdoors for the majority of the year, with a roost area for resting. Their feed can’t contain antibiotics or hormones, and the roosts must have at least two square feet per hen. The government does not regulate free-range egg farms, so you must trust the farmers. Some farmers call these eggs “antibiotic-free” or “naturally-raised.”
4. Pastured eggs: Pastured hens are kept in cages with at least two square feet per hen. The structure containing the hens is moved to different areas of the grass daily so the hens can forage for at least 20 percent of their food. They are also not allowed to be fed antibiotics or hormones in their supplemental feed.
5. Organic eggs: Hens must be raised from birth on organic feed that contains no hormones, pesticides or genetically modified organisms. They must have outdoor access year-round; when they are kept inside, they must be fed organic sprouted grains. They must also be allocated at least two square feet of floor space per bird.
