I have several pairs of black and blue sumatra from my show quality adults.... I bought the blue pair from Tom Kernan for $100. last year. The photo attached is the rooster, he is with show quality black and a blue hens. For more photos of the adults go here... http://www.flickr.com/photos/s1gnature/sets/72157617306589553/ This years offspring are almost grown.... the males are still growing tails but are already looking very promising. You can see photos of them all at this link. http://farm4.static.flickr.com/3542/3481050584_c7dcb3a82d.jpg Each bird is banded with a different color. for details on individual birds, email me. I need to sell them as pairs....mixing black and blue together will give you great lacing on the blues... you should get blue black and splash chicks from them..
