I've raised 3 batches of Cornish X-rocks. I am currently 5 weeks into my 1st batch of Rangers from J.M. Hatchery. Hands down, the Colored Rangers are much more enjoyable to raise. They really do range MUCH more than the X-rocks. Despite having free range access, the x-rocks spent way too much time in the coop and were filthy nasty birds. The Rangers are definitely slower to develop and it seems like they eat a ton of food, but for ME, they are proving to be the better choice. Just thought I would share my experience in case anyone was considering Colored Rangers.
