We did find some pictures of his adult male that he posts pictures of claiming it's cemani without it being touched up - I think it's somewhere back in this thread. I can try to dig it up for you, it might give you a clue what your babies will look like when they grow up
Edit: Found it for you. Here's the rooster he uses in his eBay ads without all the touching up. Might tell you what your babies will look like. http://www.rarebreedauctions.com/auction_details.php?auction_id=118613
Well that explains a lot.
