Lovely hens!I completely understand where you're coming from with the black laced double lacing issues, however if we continue to breed blue to blue the colour will start to fade/deteriorate. It is recommended amongst other blue laced breeders to breed back to a good black laced cockerel every other year to maintain a good solid deep blue colour. If you are concerned with the outcome of this cross I would recommend breeding the black laced boy to just a couple your lightest best laced blue laced hens. This will avoid the risk of hatching hens with a blue too dark and will also maintain good lacing. If you don't want to risk the occurrence of your blue hens's lacing deteriorated with this cross, you can always keep a black laced hen back from your next blue x blue cross that doesn't have double lacing on the back and use her to breed back to a blue, this way you have more control over lacing of the chicks because you know your black hen doesn't carry any dominant doubled laced alleles. Here area couple of the black laced hens I have kept over the years for this purpose:
