My favorite hen seems to have a big problem, but I am having a really hard time figuring out how to help her! Basically, I went out today and saw her looking "hunched" and not her usual perky self. One side of her face is slightly swollen, especially the eye area, and she's holding her head slightly crooked. When I picked her up I could see a little blood inside the swollen eye (under the eyelid, I mean), but the eye itself looked undamaged. I put her in isolation with food and water, but she has not eaten since I put her there, she's just standing around in the corner. I just checked on her and her breathing is raspy, also there's a fluid leaking out of her vent that looks maybe like yolk? I felt her belly but didn't feel anything odd, and it's not swollen. What do I do? I don't even know what happened to her. There's no blood, except what I saw in her eye, and no damaged feathers. She was in the horse paddock when I found her, so maybe a horse stepped on her? I would think that would be obvious if it was a horse injury though. Could she be ill? Any advice would be great, and I have pics if you think they could help, even though they don't show very much. She's my favorite hen and it would break my heart if I lost her.
