We process around 60-70 CX a week so at any given time, we have around 500 on the farm ranging from day-olds, to 8wks. Given those numbers, we do have some that die early of flip or have leg problems. The percentage of birds we lose early is pretty small though, around 5-7%, and that includes very early losses in the brooders of chicks who are just weaker than others. If they are raised properly, CX are fantastic meat birds who don't really suffer from issues the way many people seem to think. However, there is certainly nothing wrong with raising extra cockerels for meat either. CX tend to be more cost-efficient when you are looking at feeding them the same food in the same manner, but if you have the ability to free-range, DP birds will certainly be able to do that more efficiently. If you have any issues with crowing, I would not go for the DP birds though. You will almost certainly have dozens of crowing birds by the time they will be large enough to process. You also need to be prepared for the fact that they will not look like, or have the texture of, a market bird. They will have great flavor, firmer meat, and a rangier carcass with less breast meat. Both bird types have positive and negatives.
