Sorry no one answered before. I have been gone much of today. Please do not soak her anymore. It can stress her out more. You can try giving her a human calcium tablet with vitamin d about 300 mg orally in case she is egg bound. The yellow urates in her dropping and her swollen belly is water belly. If she is having labored breathing you could try to drain some fluid off with an 18 or 20 gauge needle after cleaning skin with alcohol. I usually don’t drain my hens unless they are having trouble breathing. Her comb color does not sound good. Make sure that she is drinking fluids, and electrolytes, pedialyte, gatorade, or sugar water with a small pinch of salt are all good. Try feeding scrambled egg with a little water.
