It is not a typical breed x breed hybrid. It is more like 4 family lines that are perfected so that when they are crossed twice will produce a "nick" that makes that generation have a certain hybrid vigor trait like rate of growth or muscle conformation. They are a patented hybrid broiler much like the cornish cross is in that it is a result of highly secretive 4 way strain breeding that a corporation developed.
grandparent line 1
grandparent line 2 > parent line A
> Freedom Ranger
grandparent line 3 > parent line B
grandparent line 4
"Freedom Rangers" are a marketing name. The "breed" or strain name is called Rebro. The strain is specially developed for the European Label Rouge program. Hubbard is the company that developed them and holds the patent. They are a cross between Hubbard's "differentiated" strain and a cornish cross type female strain. Only Hubbard knows the specific genetics behind the Redbro.
Only Hubbard has access to the four "grandparent" lines, JM either has a contract to keep the two "parent" lines to cross, or may only get access to the "terminal" line chicks or hatching eggs. This four way system guarantees that only Hubbard can produce the official bird. Two hybrids may not reproduce the "nick" that made the original hybrid special so the time and trouble it would take to stabilize this nick on-farm virtually guarantees that a customer will choose to just pay Hubbard for new chicks each time. Below is a link to Hubbard that will show you the parent strains, their specs, and you can also find things like feed conversion ratios for the Redbro etc.
