I have 3 Guineas 7 hens and one rooster. I have one guinea who is kinda a jerk. He chases the hens around and pecks at them. I just moved them all to the coop yesterday was hoping that would help but not much. He only does it if he's at the feeder or waterer and wants it all to himself. Anything I can do to stop this? I yell and clap like a crazy person when it happens and I get the what look.
