This morning I went out to check on my hens and noticed one was not outside. She eventually stumbled out and I noticed she seems to have her head cocked to one side and her feathers on her head seemed like they were all brushed to one side. I then proceeded to give them their treats (dried meal worm) and they all go in a frenzy as usuall except for her. She acts like she cant see them, when I try to feed her by hand she acts not interested. There is no obvious trauma. She dosen't seem steady on her feet. I brought her indoors and set up a little area in the garage for her with food and water. We live in the Pacific NW so it's kind of cold out here. Not sure whats going on with her. Any help would be greatly appreciated.
