I would say her loss of appetite is due to liver disease. The B vitamin thiamine in the NutriDrench may help stimulate that. The removal of all of the ascites fluid has made her weak. It is hard not to try and help drain them to help them breathe easier, but I normally do not drain my hens when ascites is suspected, preferring to let them be, and try to make them comfortable. Ascites/water belly is eventually fatal. Is her crop empty and flat?
