Jumping in very late on this thread as it seems...

I just started a new flock a few weeks ago and have been wanting a BCM....and wanting one as "true" as possible. (I had them as a child and fell in love with the breed).
After weeks of trying to look locally, I did find a local breeder that had 2 week old Black Copper Marans that are Cottage Hill rooster over Wade Jeane hens. Is this a good/true line? I bought just one to try....hoping it is a hen, but ok if not. Just looking for anyones expertise on the cross.
Thanks all!
