I'm going to ask a very stupid question ( I guess ), but I understand that when eggs are marketed as "free range", I know that means the hens were allowed to roam all around on the ground to eat bugs, worms, grasses, etc. as opposed to those poor layers in the large commercial setups. Now - here is the stupid part - do the hens have to be totally not fenced in at all for them to be considered "free range" or can they be fenced in within a large area as long as they are on the ground grazing free and still be called "free range"? I hope my question makes sense? Thanks in advance!!!
