This experiement is based off of WLR dominate white hens-- that is all I could find to purchase for my start. I was hoping to create some solid white offspring- didn't matter to me if they were dominate or recessive- as long as they were white.Your Blue laced male could be carrying recessive white, at least one female would also need to be carrying it to express it resulting chicks. Unless there is some dominant white, brought in to the mix via some white laced red blood, in which case, should have showed itself.
Recessive white chicks, in my experience, are evident at hatch, having yellow, to reddish yellow down in this line of Cornish. Going on to develop solid white feathering.
Now having said that I do have a couple youngsters that are showing some colored feathers, which are recessive white, that I suspect are possibly covering blue, or splash. I have too many white youngsters, hatched from colored stock, that I do not need for this project.
For next year, I intend to breed the BLR cock to Dark hens- even though they have WLR blood in the background, I'm thinking they should not carry any dominate white.
I did have yellow down chicks hatch, not quite the 'buff' color of the WLR ones... but my novice self did not keep them seperate, or no any better.
