Egged On

I was at a local Whole Foods where I saw a poster on the wall.  It read

All eggs in our dairy cases are cage-free or better.

Better?  They're not referring to the quality of the eggs, but the treatment of the chickens.  So what's better than being cage-free?

Do the chickens receive massages while they're laying?

Do they get vacations in Cancun to work on their tan?

Or maybe they're just referring to their bacon, which they think is better than eggs.
