I have this hen that my rooster has it in for. He treats her badly and different from my other hens. She's is scared to eat in his presence or look at him. She screams loudy and drops to the ground. So I now have isolated her in my temporary small coop. My question is can she recover and act like a normal chicken again. She acts like she has ptsd. I feel absolutely terrible for her she screams if I even get near her
