I've heard a lot of great things about Freedom Rangers - especially the ability to keep them as a self-sustaining flock of meat birds, unlike Cornish Rocks. Then I came across this article: http://www.motherearthnews.com/happy-homesteader/wrong-about-freedom-rangers-zb0z10zgri.aspx Are Freedom Rangers too good to be true? Are they actually hybrids? And, for that matter, does that mean Freedom Rangers could be crossed with Cornish Rock to produce another burst of hybrid vigor? Or crossed with another fast growing and/or meaty breed for that F1 vigor?
