Hi, first year chicken owner, and I have a flock of mixed aged chickens, From 2 weeks to 15 weeks. I’ve separated them into 3 mini flocks based on age. The last 2/3 weeks I’ve slowly been integrating everybody. Things have been going well, every once in a while one of my big girls will side eye and peck a smaller chicken but nothing major or serious injuries. As far as I KNOW I only have one rooster, a 10 week old bantam. He has been “dominating” his little flock, doing his cockerel thing. But he’s normally scared of my bigger girls. When I put everyone in the yard, the bigger girls will clique off and he’ll clique off with his girls. But the last few days he has gotten brave, moving closer to the big girls, and not backing down when my head hen does the stare down thing. And the past couple days he’s gone after them. He grabbed her tail, jumped on her back…well you know the drill. Now the big girls aren’t scared of him but they don’t confront him either. They give him a wide berth when he walks by. My question is: is his behavior something I should try to stop? Or is he trying to let my girls know he’s the rooster? Or..what? I will say there doesn’t seem to be any damage done, no cuts or feather loss. He is MUCH smaller, 1/4 the size of the big girls. I know there’s a pecking order, but I have no idea how a rooster becomes ya know the head chicken of the flock.
