I suppose some do some don't some will some won't I personally won't raise them with roosts. These birds grow so fast that that they are outgrowing their bone structure as it is, they can suffer leg problems simply from living out their life before even reaching the 8 or 9 week butcher date, I certainly don't want a chicken known for bad leg issues falling or jumping from a roost, I have layers get knocked off the roosts sometimes when they shove around trying to get the best spot and it worries me that they may injure each other and they are nowhere near as heavy as a Cornish X. I have read many recommendations against providing roosts for these reasons and others such as breast blisters.
Then you have the crowd that feels they need to make the chickens life more "enjoyable" by providing the activities chickens normally have such as roosts and free ranging etc. To each their own but I say Cornish X are plenty content laying on the ground and gorging themselves with food, that is what they were bread to do and that is what they excel at. If you do provide roosts I would only put them a couple inches from the ground so they can almost step up onto them, at least that way it will hopefully avoid injury.
