My dad has about 5 buffs that he put in the pen with a rooster. The rooster had been injured by a hawk prior to this. They did well for a couple of weeks but now they are attacking him. If dad had not gone out there last night, they may well have killed him. Could they be doing this because he's only feeding chops and not a laying formula? They're a couple of weeks from their first laying. This poor rooster has been through hell. I had to take him from the city to the farm because he crows so much and so loud. Any advice would be appreciated.
