I've got 4 cockerels that are currently 13 weeks old, and they are in a pen with a 9 month old rooster, a hen, and a 13 week old pullet. Right now, everybody gets along with no drama, but at what age would you worry about them challenging my older rooster for mating rights? I could process them next weekend (14 weeks), but after that I will be gone for almost 2 weeks, and someone else will be watching my chooks. I don't want any drama to happen while I am gone. Should I process them all at 14 weeks, or do you think I can wait til I get back (16 weeks)? Or maybe I should just do the two that are already crowing, and wait on the other two?
