Supportive Care for Hen with Water Belly?

[OversaltedEgg]

My 2 year old rustic rock hen was just recently diagnosed with water belly. She went downhill quickly and we ended up taking her to the vet. I have chosen to support her and try to keep her alive with the time she has left. I have given my chickens shots before but I’m not comfortable with draining her myself so she will have regular appointments at the vet for the draining. I believe her water belly is caused by liver disease since the urates in her feces are yellow. She is currently separated from the flock. She will eat and drink water, but she constantly shows disinterest in food. I have given her mash, scrambled eggs, nutridrench and oatmeal so that she can get her energy back. I can see that she is fighting and she does have energy but she will occasionally stand still for a couple of minutes. Her breathing is audible when you are near her but she isn’t gasping for air and there isn’t any other signs of respiratory distress. Occasionally I do hear a clicking noise coming from her and I am unsure of its origin. Her comb is still red and plump so I pretty sure she is getting oxygen throughout her body. And advice?
