I have 6 roosters right now. They each have their own harem of hens. I have between 80 and 100 total chickens. One summer I took in a couple of unwanted Roos and then I accidentally got two more as grab bag chicks. BUT the very first roo I had was a homicidal sociopathic bad ass that I had to put down because he would attack anyone near the barn. The Roos I have lost over the years always died defending the girls. I worry much less when a group of hens is out when they have a roo with them. This batch pretty much get along they have worked out their issues without me seeing a lot of fighting or blood.
