I think you have a blr roo amd splash hen, so you would get the 50% blr, 50% splash from this pair.
I have heard that some breeders prefer this pairing because you avoid getting black laced reds. Here is more combinations if you want to take a look.
As far as quality I have no idea. BLR have not been admitted to the American standard yet, they are judged just using wyandotte standards for body shape. There is a draft for the coloring here, but it isn't official by any means.
Good luck getting postings on quality.............They are pretty rare and not a lot of people have experience with them..................They are beautiful..............The whole reason we ordered chicks! I will be following this post...........I'd love to hear about quality too!
