I've learned that the White Cornish is the sire of choice for Cornish Rock X's, and possibly for the Freedom Ranger meat birds as well. Can anyone tell me what it is about the White Cornish that make them such a popular meat sire? My wife and I are thinking about trying to raise a version of our own meat birds. We know they won't be as good as the ones you can buy. We're figuring there's some kind of hybid vigor associated with the Cornish that unlocks when it sires, but why is it always a terminal sire? Does it matter which breed of hen it's mated to? I know the Freedom Rangers are probably Barred Rock or Speckled Sussex hens. Thanks.
