Earlier I wrote about cage free eggs with a rather sarcastic tone. I assumed caged in this context meant the chickens were confined to a chicken house but able to walk around. This morning, the Diane Rehm Show had a guest who talked about cage free and what it meant.
Here's a link to a video showing hens in laying cages. Apparently, they're confined like this most of their laying life.
