Commercial cross is a White Cornish rooster over a White Rock hen.
Purebred Cornish are naturally very large breasted with thick sturdy legs, but they do not have the fast growth (overgrowth) that the hybrid vigor provides. I used to have Dark Cornish (standards), they have tight feathering, so they are a LOT heavier than they look.
I had a few cornish X meat birds one year that. They are extremely slow when they are full grown, the pullets will lay, but as much as they EAT the eggs are not a good reason to keep them. The ones I had also had a very shabby life due to persistant bumblefoot and breast blisters. These birds are not designed to live to adulthood. It is a sad truth, one must decide if keeping something alive for the sake of keeping it alive is really the humane thing to do. There are some fates worse than death.
