I went outside to find one of my full grown rirs laying behind the coop immotentlouse and growling, she would not move, I had to pick her up and put her inside. Once inside she still just stood the growling and looking around. Do you think she was traumatized by some animal trying to eat her? I tas 2:25 pm when I went out there so the only predator out would be a hawk and I did a thorough look around and didn't see anything. What could have happened? I am worried!?
