My almost 3 year old Australorp, "Blackie", is suffering. She does feel lighter around the breast than usual. Her lower abdomen is filled with fluid. It feels squishy- not like a tight water balloon. Does not feel egg bound. She is lethargic, standing with ruffled feathers and closed eyes. She has exhibited the symptoms above for 2 days now. There are no other birds exhibiting symptoms. There is no bleeding or other signs of trauma. Her vent looks normal. I started feeding the flock fermented feed about 2 weeks ago. I noticed she was "off" yesterday morning when she didn't eat anything. She has not eaten or drank anything since I began monitoring her. Her crop is completely empty and she hasn't pooped at all. So far, I have her isolated in a dog crate in the house as comfortable as I can get her. I am considering draining the fluid myself with a syringe and administering an antibiotic. I am willing to cull to end suffering.
