My jersery giants and australopes are almost 2 months old now... I have 5 cockerels and 5 hens... Iv noticed the cockerels starting to assert themselves and have 1 cockerel that has taken the blows more than the others.... Is it time to separate? Can I have 1 cockerel with my hens and keep the rest of the cockerels together? And does the run need to be where they cant see the other hens?
