Hey there! I have a coop of like 20 chickens all will be 5 months old tomorrow. 6 are roosters & they all live together. Only 2 crow and so far no real fights. What age do I need to seperate them? If they are all happy can I leave them for awhile. After they start laying I will group them up and seperate so I can hatch chicks....but for now are they just fine?
