We believe our chicken was attacked by a hawk or crow. I hear a scream outside 3 days ago and ran out to find her lying face down with her eye swollen shut (or missing?) and her neck twisted. I moved her into her coop on her perch. She laid an egg then made it down from her perch to the bottom of the coop where she's been ever since. She is not eating but appears to be drinking water. I know the twisted neck means neurological issues. Is there any hope for her making a recovery? Is there anything I can do? I really don't want to put her down if it is not necessary. Any help is appreciated!
