In regards to crossing rocks to andalusians. If it was me, and depending on if i had enough birds to do this with, which really wouldnt have to be very many,I would split the line into two. In line one, you could just breed the black rocks to blue rocks and hopefully improve lacing that way, and just continue to linebreed those, while working on type, color ect. Who knows, maybe you'll find this will be enough to improve them.
In line two, take a few blue rocks to outcross to Andalusian, if nothing more than to experiment just to see what happens. This way you still have some pure rocks if the Andalusian cross doesn't work out. And if it does then great, now you have new unique line of Blue Plymouth Rocks. Eventually you could cross the AndalusianXRocks back to the pure Rocks.
I would always maintain some pure rocks with no Andalusian influence so you always have something to improve your type and you don't end up with all crossbloods. Don't put all of your eggs in one basket so to speak.
As for skin color, which is related to shank color, the white is dominate so once all white skinned(blue shanked) birds have been culled out you won't have any problems with slate shanks. With enough offspring to pick from, that can eliminated in one generation. The next step of reducing the pigment in the dermal layers of the scales will be harder and you will still end up with dark shanked birds, however the skin color will be right. its just then a matter of selection to lighter (more yellow) shanks.
Just my opininion.
Also, nice to see someone out there working with Blue Rock largefowl
