I have one rooster and lately he has been showing aggressive behavior. He pecks at me whenever I go into the coop to clean it, change the water, or refill the feeder. He also pecks at the hens. And they aren’t just little pecks, they are pretty hard. I was hoping the behavior would go away on its own, but if anything it has gotten worse. I’m worried for The hens. Is there anything I can do to reverse the behavior?
