Pros: Voracious foragers, tough as nails, develop quickly and have the deepest muscling.
Cons: They come from the hatchery needing some probiotics in their systems.
I've raised two batches of the CX and are incredibly impressed with their foraging abilities, their activity levels and their tough nature. These birds can get an injury and brush it off like it never happened. Heal up so fast and well that you can't tell who was injured, even when doing the processing later.
They have a great feed conversion and I've never lost one to unexplained death. They will range farther and forage longer than any breed of chicken I've ever raised..sunup to sundown out on pasture and in the woodland.
They do well on fermented feed and full free range. Grew them slow, used fermented layer mash and whole grains. Healthy chickens that fill the freezer like no other breed. Can't say enough positive things about this breed.
