I agree with the majority....they are clearly not discussing true free ranging here but just the USDA "definition" of it. It would be like a backyard flock of 10 in a house and run that would suit 4 chickens, that have a bare and small run, deep fecal litter, and no good immune systems because they are fed antibiotics in their formulated feed. Yes, I could see all those things happening in a smaller model in a backyard flock....wet and dirty conditions, too small an area, compromised immune systems.
In a true free range operation, there would need to be adequate space, land, etc. for a large flock. Deep litter is fine if tended well....fresh litter spread, prevention of a litter "cap" developing over wet litter, removal of any wet litter to prevent bacteria and fungal growth, etc.
To me this sounds like propaganda spread by CAFOs because they get less for their product than do so-called "free rangers" in the supermarket. The public is gullible and are fooled by packaging and the commercial "free range" operations know it, so they invest in better packaging and have nifty little labels with healthy info on them.....all the while charging $4.95 for 6 eggs!
I wouldn't consider anything BUT free ranging or chicken tractors...and I've never had illness in my flocks nor cannibalism of any kind.
