“Free-range” means that the animals cannot be kept in cages within the barn and that they have seasonal access to outdoor pasture. You may also see the term “cage-free” which is often used to describe the barn environment for laying hens for eggs.
Products that are labeled “free-range” or “cage-free” are not organic. These terms only refer to one aspect of how the animals are raised. Organic standards regulate the barn environment and require seasonal access to pasture, but also require that the animals are fed an organically-managed diet, and that the outdoor pasture area to which they have access must be maintained to organic standards. In addition, organic regulations require that the animals are raised in lower density flocks, allowing the birds more space within the barn to move about and express natural behaviours, like flapping their wings and dust bathing.
