What Are Cage-Free Eggs?

A Guide to Buying and Understanding Cage-Free Eggs

More and more eggs at markets have the label "cage-free" stamped on their carton. The moniker certainly sounds good—who wants to think about being in a cage, after all—but what does the label actually mean?

"Cage-free" marked on a carton of eggs means quite simply that the hens laying those eggs are not kept in cages. Again, that sounds good but the label has a fairly limited legal definition and the practices of some farmers only following the letter of the law make this question more complicated than you might think.

The Basics

In theory, the hens that lay eggs labeled "cage-free" are free to walk around the hen house, to perch on roosts, and to lay eggs in nests. 

This is in great contrast to most laying hens, which are kept in cages so small that they can't fully open their wings, much less walk or move about. 

The Best Case Scenario

Perhaps the eggs labeled "cage-free" also have "free-range" on them and come from hens that were allowed outside more or less at will, at least during the day. They may even have had green pasture to explore, allowing them to exhibit the natural behavior of hunting-and-pecking for seeds and insects that grow in the grass. 


"Cage-free" means the hens were allowed to wander freely, but that wandering can be limited to a hen house. The hens may still live in over-crowded and unhealthful conditions. The "free-range" label requires that the hens be allowed outside. That said, the amount of time they are allowed outside and the conditions of that outside area are not defined, so it is possible that a crowded henhouse would have a small door at one end leading to a small concrete space that the hens are theoretically allowed into but which in practice isn't much of an improvement.


"Pastured" has no legal definition or third-party verification, but is usually used by small farmers who raise their chickens on natural pasture—roosting in a hen house at night and roaming on pasture during the day, hunting and pecking for their food and exhibiting other natural behaviors.

"Cage-free" eggs are also fairly widely available at mainstream grocery stores, unlike the less common "pastured eggs."

The Reality

That said, "cage-free" chickens are kept in hen houses, often in cramped conditions, and may or may not have access to the outdoors or pasture. Without other or further labels explaining how the hens who laid the eggs were raised, "cage-free" is better than nothing, and are a solidly better choice than most commercial/industrial eggs, but they are not the gold standard.

Why Egg Labels Matter

For those looking for the best quality eggs from hens allowed to exhibit natural behaviors, pastured eggs from hens raised by small farmers who may even invite you to visit their farm, so proud are they of how they treat their animals, will prove to be a revelation. Since the hens were allowed to get some of their diets from greens and plants and insects, their yolks aren't just yellow, but verge towards a bright, sunny, almost orange color. The whites are full-on bouncy. They have an intense eggy flavor and color that makes any egg dish, even a humble soft-boiled or hard-boiled egg, shine.

At the very least, getting "cage-free" eggs means you've avoided supporting the worst of the egg industry's all too common practices.
