Egg Carton Labels

Introduction

When buying eggs, consumers often encounter various labels on cartons, which can be confusing. The conditions in which hens are raised can vary significantly, and each label provides insight into how the hens are housed and cared for.
This fact sheet helps clarify common egg carton labels. It explains how chickens are housed, defines standard egg-related terms, and highlights some rules that guide the industry. Whether you are looking for more ethical options or want to understand the labels on your carton, this sheet will help you make more informed choices when purchasing eggs.

Conventional Cages

• Chickens are kept in cages with around 67–80 square inches per hen, generally in groups of 4–9
• A manure collection belt is located below the cages
• A feed trough is in front of the cage, and water nipples are at the back
• An automatic egg collection system is usually in place

Colony Cages

• Similar to conventional cages, but larger
• House larger groups of birds (generally around 30–60)
• Stocked at 67–116 square inches per hen

Enriched Colony Cages

• Similar to colony cages but include additional furnishings
• Furnishings may include perches, nest boxes, and scratch pads
• Generally will have at least 116 square inches per hen

Cage-Free

• Birds are not raised in cages
• Housed in barns on the floor, on slats, or in an aviary (tiered) system
• May or may not have outdoor access
• Provided amenities like perches, nest boxes, and scratch areas
• Stocked at 1 square foot per hen or higher
• Pullets (young layer hens) need to be raised in a similar system
• Generally could be certified as California Prop 12 compliant

Free-Range

• Similar to cage-free but includes outside access
• Must have outside access for a minimum number of hours per day and a minimum number of days per year (depending on factors such as disease risk and weather)
• Requires 1 acre of range for every 2,000 hens
• Includes requirements for outside drinking water, shelter, and vegetation management

Pastured

• Similar to free-range but with larger outside range area

Organic

• No antibiotics are used except when medically necessary
• Must be allowed outside access, similar to free-range and pasture systems

No Antibiotics Ever

• Hens are never given antibiotics
• If a hen becomes sick, they must be treated and taken out of the system
