"Cage-free" refers to a method of farming where animals, typically hens, are not kept in small cages. Instead, they are allowed to roam freely in a barn or indoor space, which can lead to better living conditions. This practice aims to provide more natural behaviors, such as nesting and foraging. Cage-free systems can vary in size and management, but they generally offer more space than traditional caged systems. While cage-free does not guarantee outdoor access, it is often seen as a more humane alternative to conventional farming methods, promoting animal welfare and better quality of life for the animals.
