I have a 5 month old rooster that is mating some of my pullets who haven't started laying yet. They are a couple weeks older than him but they all pretty much grew up together. All of the hens stay away from him, young and older. The older ones put him in his place but he retaliates. He's not showing aggression otherwise but the older rooster verbally disapproves of his behavior but hasn't done more than run at him so far. Last week I was crouched toward the ground to feed them an apple and he hopped on my shoulder but I just brushed him off. I noticed that no one wants to roost by him tonight. Is his behavior normal?
