Recently, some hens were picking on my EE, so I turned the water hose on them. Didn't get them *real* wet; just enough so that their attention was averted to shaking and preening for a while. I stayed close and, sure enough, once cleaned up, they started bullying again. So, I let them have it again, especially the head bully. That did the trick. Now everything is peaceful at the 7 Biddies B&B.
