The cornish cross males are all but guarenteed not to - leg or pelvic breaks, heart attacks.... I have heard of some that manage to keep females free ranging and active enough to lay. This particular cross of yours from Cackle I dunno about. They do say not the health issues of the CX (frankenchickens) but I'd be surprised if the males make it that long and/or that they'd breed true. Best place to ask is the Hatchery - they would know thier birds - I'm just winging it.
