ok I am pretty sure I can tell my cockerels from my pullets they are about 4 weeks old. I should put the ones that will be processed in a separate brooder now and give them broiler crumbles right? I would have liked to start them on the broiler crumbles from day one but since I was unable to sex them I kept them all on starter feed. I am thinking they should be ready for processing by 10 more weeks right?
