I did not finish mine in the French way . but I did cook it in a traditional French salt crust and eat it. It was noticibly different in texture and very succulant. My birds free range on about 1/2 acre eat a lot of grass and eat organic crumble. The flavor was not terribly differnt from my marans but the texture and tenderness was outstanding and he was bigger much faster.
I didn't weigh him but the 2 of us ate it over 2 nights
