I have not been a chicken owner very long, and am in total shock. We have a sick chicken. It is one of our barred rock hens, she normally does not let anyone get close to her let alone touch her. So that was the first sign. I noticed she was not running so I picked her up (with zero struggle, again unlike her) and her eyes look all swollen and drippy, as well as some dripping from her beak. She also just smells.... off. What do I do? HELP!
