Hi, This is my first post. I have an older hen (5 or 6 years), she has been apparently normal and healthy. When I went to close the coop the other night, I found her lying just outside the door (in the rain, poor thing) unable to stand up. I tucked her in the safe box inside the coop with some food and water, but figured she probably wouldn't make it till morning. Well, that was 4 days ago, and she is still eating and looking alert. However, no use of legs. She is moving her wings and tail. I am obviously worried about Mareks and can't find online if that has such a sudden onset (my daughter is in the run daily and would have reported a chicken seeming unwell or off). My other thought was a predator injury, although nothing seems obvious. Any thoughts? Thanks so much in advance, I know she is an older chicken but if there is something I can do to help her, I would like to.
