Bresse Chickens have an 'Applelation' and like Kobe beef, individuals are trying to convince buyers that thier American raised products are the real thing or as good as the real thing, NOT.
My chickens come from a local grower who grinds his own grain from local sources, raised 'free range' so to speak. It's as good as your going to get here in the USA.
Agricultural products just do not travel because the final product is the result of many local factors.
There is no Kobe beef outside of Japan, there is no Bordeaux wine outside of France and thier aren't any French chickens outside of France.
Don't waste your time or your money. Find a small local grower, go to his place, see exactly what he is doing and taste one of his chickens. It will be better than a supermarket bird and probably a lot less expensive then a 'French' chicken!-Dick
BTW, interestingly enough, when the laying hens are at the end of useful production, they are sold and we have found them to be very flavorful!
