Ok I am hoping someone can help me out. One of my Hens was doing fine one day and the next day she wasn't able to walk. So I am feeding her and giving her water from a suringe. She went from not being able to hold her head up to being able holding it up. She trys to get up but came not. How long should I allow this to go on? What should I do? I am confused on what is going on with my hen. Please help me!
