Cornish Cross don't get good feather coverage, so I suspect you will have to provide heat if you want to raise them in the winter.
If you are raising them in stalls, look up how to build a brooder hood. The birds go under and you aren't paying to heat the entire barn. I think I've seen them called a hover. That's the way chicks used to be raised.
