Our babyroosters are almost 5 months old, and they occasionally spar but they break each other's fights up and the Big Daddy Roo breaks them up, too. At what age does this fighting become less frequent? We've only had an occasional tiny bit of blood. They are 5 babyroos and 4 babypullets living with the original 3 hens/ 1 roo for a total of 13 chickens. So far, everybody gets along well, sometimes the little babyhens squat for mating which the babyroos are happy to oblige. But , umm, they're siblings (should we stop that?) Here's some, they're all quite small and banty: So, at what age does this "Testosterone Poisoning" generally quiet down?
