I recently bought a trio of bantum Golden laced cochins. The roos is almost solid black with minimal gold on his chest. The nens are better, but still to black, if I cross with some buff cochins would that help increase the amount of gold in the birds? is the black in the laced birds the solid color like it is in the barred birds? or is the black the lacing and the birds base color gold? Thanks for any help or advice.
