If the egg was laid on a free range ...then is the egg found in the free range not a free range chicken egg?
Can the egg go for a walk whenever it wants?
Is that the definition of free-range?
(of livestock, especially poultry) kept in natural conditions, with freedom of movement.
"a free-range, corn-fed chicken"
(of eggs) produced by birds reared under natural conditions
Apparently, that is not the requirement of the definition. Of free range.
