If a traditional Cornish Cross is made from a White Cornish rooster on a White Plymouth Rock, what would happen if you put a Dark Cornish rooster on a Black Rock hybrid. A color negative Cornish Cross?!
I wish making a CX was that easy..Unless you are good and into corporate espionage we will never know for sure what they are. I would not put it past them to not even have cornish in them...just to throw us off the trail.
