Read on and check out the definition for free-run chicken as well.
Please note: “Free-Range” and “Free-Roving” are interchangeable
Excerpt from Ecoholic
“These hens get to see the light of day and snack off the land. Not a government regulated term. Only backed up on certified organic eggs.”
From the BC SPCA website
“Hens that are raised in free range systems are free from battery cages and are allowed some access to the outside. As with free-run housing, free-range systems do not necessarily provide more space than conventional battery cages, and are not required to provide resources such as nest boxes, perches, or a substrate for dust-bathing.”
