2 weeks ago we found out our second flock (it's just 2 chickens who we got later and live in their own coop, everyone shares a yard and they tend to share nesting boxes) has a rooster! Good times. Before we realized we had anther rooser, Roo 1 (R1 from here on out) started overmating one of our hens. He has been a generally docile, respectful rooster until this point. I made her a saddle once she started balding, and now he is tearing up her wings. Now another hen from flock 1 is starting to show signs of overmating. Of the other 2 hens, one must have realized he was trying to assert himself, and she started submissive squatting when he was around, only to have him not mount her and instead rip out her head feathers. I watched him do it 3 times. The non-overmated 2 hens from flock 1 avoid R1 and are letting R2 mate them. They literally sneak to the nest box and spend the rest of their days out front where R1 can't get to them and when they are in the yard, run from him. I want to let them all rework this on their own, but i am getting to a point where i can socially see that 3 of the 5 hens want R1 gone and the other 2 are being injured by him. Is it time to intervene?
