Final answer:
Free-range chickens are distinguished by being allowed to roam freely in an enclosed space, which provides a more natural and humane environment than confined industrial settings. This method of poultry farming aligns with a movement towards better animal welfare.
Step-by-step explanation:
What distinguishes free-range chickens is that they are allowed to roam freely in an enclosed space, usually outdoors, where they can exhibit natural behaviors such as walking, foraging, and dust bathing. This contrasts with chickens that are raised in more confined settings like battery cages. It's important to note that free-range conditions can vary, and the specific regulations and standards defining 'free-range' may differ by country or certification body.
Free-range farming is part of a broader movement aimed at improving animal welfare and producing food in a more ethically responsible manner. The history of domestic fowl, like chickens, shows that these animals have been an important part of human cultivation and diet for thousands of years, with their care and breeding practices evolving over time.
