I am sure that I will never find it again but I read a legit article about how 'cage free' was actually worse for hen welfare than cages.
Cage free sounds like they are outside - but actually they are just all stuffed in a huge concrete floored barn so they are very over-crowded and cannot escape the pecking from their neighbors.
Equally 'free range' is a misleading label because that means that there are openings in the big concrete-floored barn so that the chickens nearest the opening can get outside for a few hours - but there are so many chickens in the barn that very few of them ever make it to the opening.
The only reliable label is 'Certified Humane' because that is independently verified by an organization who focuses on hen welfare.
I think it was National Geographic where I read it.
Haven't found the original article but came across this on free range:

I am so happy my kiddos can dig, and run, and jump.... kill snakes... eat bugs.
