From everything I have read flocks do better when there are only a few roosters to many hens but half of all chickens that hatch are male. In captivity people tend to eat the surplus roos but what about feral/wild chickens and Red Fowl? Are wild flocks composed of half males? Do the roosters who can't climb the ranks roo go off on their own? I'm sure some roos would attack and kill each other but if there was 1 roo for every 10 hens like in captivity that would mean a 90% male mortality rate which seems far too high to me.
