I've heard a little about them, and am contemplating getting a couple dozen in the spring. But I'd like to know if they are a specific breed, and can I hold back a cockerel and a few pullets to raise my own in the following year or two, or are they a type of chicken like the cornish crosses? I know cornish cross chickens really can't be raised for re-breeding. Also, are "Red Rangers" the same as "Freedom Rangers"? I'd like to hear what those of you who have had experience with these birds think. I have a neighbor who thinks very highly of them.
