Hormone-Free is nothing but marketing (yes, we are guilty of using it because people want to see it). When you see a "hormone free label" it makes it feel like that particular chicken is healthier and more natural than other options, it's probably not. The FDA hasn't approved the use of hormones for raising any type of birds (or pigs) that will be used for food, so the hormone-free label is completely unnecessary. All chicken legally sold in the US is hormone-free.
