This is kind of old but...
Simplest fix: order some Cuckoo Dorkings from Sand Hill. You'll get nice meat type, fifth toe, and the correct color skin/shanks. I've heard the egg color from Sand Hill birds is also pale to white, though I'm not sure about the Cuckoo.
Plus, I just really want to see some photos of the Cuckoo Dorkings from Sand Hill!
I think if you used the Cuckoo Dorking, you might actually create a really good dual purpose Houdan....(Or any Dorking, really, regardless of color.)
