I remember when "free range" chicken/eggs came around. The definition of that is wild. Opened my eyes to how bullshit all of the US food labeling stuff is. It means something like they have access to 2 square feet of outdoor space access. But theres like no rules on how often they need to be able to use it. So you can just have thousands of chickens you lets cycle through a tiny outdoor area once in their lives and it meets the requirement. It's a joke.
Supersize Me 2: Holy Chicken! covers this and is definitely worth a watch. He sets up a fried chicken restaurant and establishes all the minimum criteria to promote your food as free range/organic/healthy etc when it really isn't.
There is a thing now in Germany called "outdoor climate" for beef etc. It's supposed to be the second best form of farming and literally means: There needs to be a window somewhere.
In most countries, organic mostly just means that the feed they use is organic with maybe a few minor other additions, but regardless I wouldn't trust any claims of anything actually being antibiotic-free.
Sadly, what it means in practice is that access to outdoors is strictly controlled or forbidden, and the factory will probably kill all the chickens and throw them in the trash if a disease outbreaks. There's a bunch of talk now in big ag about biosecurity, and how small farms are a risk because they can introduce disease. How about actually have a natural farm instead of a micromanaged industrial operation, and then maybe the animals will be robust to illness.
