Your welcome, about 5-6 months old. I always wait until they have molted due to the sheath feathering in the skin. I like a bird with a smooth breast and no bumps from the new feathers coming in. They usually weigh about 5-6lbs. Beautiful meat. I experimented once taking a couple of my Bresse hens putting them with my white rock rooster, I got some pretty nice size meat only birds, but the taste was not as good as the Bresse meat alone. The chicks I hatched out went right to the freezer, only had a 75 % hatch rate as well. The hens were the better tasting of them.
