I just saw thid. How is she doing today? Is she eating, drinking, pooping, chickening? Is her crop empty in the morning before she has anything to eat or drink? Can you part her feathers and look for bruising, chickens bruise green. Did the hawk actually have hold of her?
It's always good to treat for shock, especially if they go off their feed. Add 1 tsp sugar to 1 c warm water, plus a pinch each of salt and baking soda. Shake or stir to dissolve, then hold some up to her beak in a small cup. If she won't drink, dunk her beak in or put a drop on your fingertip and put it on the crease of her beak. She should swallow. Repeat until she refuses by shaking her head. Let us know if she starts eating after that.
You can add water to her regular feed to make a mush or gruel and see if she will eat that but remember a dehydrated hen can't eat. So try to get her drinking. Then try a little scrambled egg (no salt). Keep us posted snd good luck!
