I have another sick hen that maybe I've caught in time. I have her on Sulmet. I've syringed water into her several times today and have fed a little egg/yogurt mix once. She's accepting the water fine. Food's okay but I haven't given her much. How often should I do this? Should I feed her as much as she'll eat at one time? I've got some crumbles soaking now and thought I'd try those soon. I can do more yogurt but again, how much? Thanks!
