Hello, I need urgent advice! I have a 4 year old home hatched hen. She’s suddenly off her legs. Yesterday I found her in a nest box with her legs splayed out behind her and wings out. I thought she was dead but I took her out and she was alive and unable to stand. I took her down to the house and she ate crumbs of bread and meal worms an a little seed. Drank water and seemed a little perkier so I left her to see how she went. Today she is just the same as we was but her eyes are mostly shut. I have given her a warm soak and dried her and she has had emeraid syringed down with vit b12. She ate a mouthful of scrambled eggs but is entirely lifeless apart from occasionally looking around then closing her eyes again. I fear I’m not going to manage to bring her back round but if anybody can suggest a magic cure I’d try anything
