Essentially all commercially farmed eggs are from caged hens, unless either you live in an area where caging hens is illegal, or the eggs are explicitly advertised as being cage-free.
Furthermore, being cage-free is not sufficient to reap the benefits discussed above. "Cage-free" hens are generally still crowded so tightly that they do not move around much, and do not have access to the outdoors.
Pasture raised hens do have the benefits described above, and essentially no commercially farmed eggs are pasture raised except those specifically advertised as such.

This is a silly thing to say. Of course if a chicken is pasture raised it'll be advertised as such on the carton, those eggs go for 3x-4x as much per dozen!
