The recommended way to feed Cornish X is 12 hours with feed then 12 hours no feed per day after the first 2-3 weeks of age. Otherwise they will grow too fast and then may have health issues. You can start to butcher them at 30 days for game hens, 42 days for 3.5 lb friers or at 56 days for roasters. Beyond that you may experience losses as they were developed for the broiler market only, NOT as dual purpose. Good luck.
