so I've read that with meat birds you give light for almost all 24 hrs out of the day to promote eating and growth. But they get processed at 7-9 weeks of age. I don't think I'm comfortable going to such 'extremes'. Can you raise them like normal chickens (dawn to dusk and then coop)? If so, at what age do you process them? We haven't picked a breed yet, so if there are any more suited to a 'regular' schedule, which should I buy? ThAnks in advance for any info!!
