Yep, I've seen all males going for 'morning love'.I have noticed it seems worst first thing in the morning. I will try separating the submissive one and see if his brother tries harder to dance.
I am reluctant to get rid of them because I got them for their survival instincts. I had coons and wanted back up for my increased security. Well I was kept away from home one night. Found 1 dead dry chicken, a duck pond with bloody water, 2 damp roos, and bloody coon tracks. They earned their keep.
I do believe that they can be better behaved with the ladies and that will make for a happier flock.
They are confined from about 2 hours before dusk until about 1 hour after dawn. There are multiple things to run behind and around. No pinch points. I'm still trying to convince my new ladies to sleep in the coop so we have multiple sleeping boxes right now.
So at what age are they considered "mature roosters"?
Separating just the one is not going to make them mature faster.
Age is your biggest problem right now, it's gonna take time.
Coons getting into the coop or birds were left outside overnight?
Males can help defend, but usually just speed bumps.
What does this mean?
"multiple sleeping boxes"
If coop is crowded, it will only make things worse all around.
