I have two roosters that were raised together and are now almost 7 months old. Flock dynamics... 3 of the original flock left, 2 of chick are roosters, 3 left of the second batch and 5 bantys of the third. I have two coops, one 4x4 and the other 4x5. 4 of the newest prefer the new coop. So the two Roos, and 5 hens generally roost in the 4x5. I went out to the coop today and noticed blood on the screen. After all the chickens raced out, my RIR roo was still in. I looked and he wasn't moving. So I opened the back of the coop and lifted him out and he had a bloody comb and his eyes were bloodshot. I grabbed him, brought him inside, cleaned him, gave him vitamins and warm rice and just left him alone for a bit. I brought him back out and my other roo bristled at him. Am I now just seeing the cock aggression? I have noticed that my Acona roo is confrontational in the mornings and usually spend about 5 minutes proving who is queen after I let him out. He bristles and struts at my feet, I shoo him away and chase him. He has not been mean to me and usually seems nice to the hens. Should I seperate the two roos into separate coops now or do I cull one?
