My Chicken Will Not Eat

Emerald my chicken was attacked by a hawk a while ago. She has recovered from her injuries. She would eat until she went back to the other chickens. They not remembering her attacked. After that she stopped eating. I think it's loneliness. We have been force feeding her for about a week. She is a American Red Sex-link. I was wondering if she had chicks to take care of she would eat because then she will have a purpose.
