Silly question, but since CX are by definition a cross couldn't the overall outcome vary with each chick, even if they're all from the same parents? Sorry I'm still a bit rusty on genetics...Same source as far as I know.. the feed store told me that they were from a local hatchery. I am really surprised by the difference in body type. This second batch is more active, and less feisty with feed. Their tails are also higher and their legs not as thick.
