Oh no. Poor Peanut. I have been down this road a few times and as
@BY Bob mentioned, I have drained my own hen. As you know, treatment outside of draining would depend on the cause. In Ruby’s case, hormones, along with occasional antibiotics, kept the swelling at bay for years. However, her fluid was deep behind a thickened abdominal wall and had to be drained by an avian vet using ultrasound to guide the needle.
With Lucky, draining helped quite a bit and I was able to do it myself. I used these
butterfly infusion needles with a 60cc luer lock syringe. (I had tried before with a regular needle attached, but it seemed more dangerous.) She would continue to drain for hours and it provided almost immediate relief.Do you think you could get your hands on supplies?
Aspirin can also help ascites. I would give one 81mg aspirin to a standard sized hen over 5 lbs. After that, you can cut them in half and give half as much. I preferred a whole one. It’s only for a couple (2-3) days and not long term use. Lily of the desert aloe detox also seems to help, but it takes longer. You can syringe 4cc orally, but it takes awhile not to aspirate. I like to put a full “shot” (1.5 ounces) into some damp feed and let them all eat it. They love it.
I have also had hens swell up and then reabsorb the fluid on their own. Millie used to swell up during laying season and then it would subside when her hormones changed during molt or broodiness.
If Peanut’s ascites came on quickly, I would recommend an attempt at draining to buy time as Bob suggested. I’m so sorry for both of you. This is so hard. I have done everything from treating as much as possible and taking to too far to immediately opting for euthanasia, as well as everything in between. If an avian vet could see her, that would be great. They just might not know what’s going on, either.
Best wishes, good luck, and please keep us posted.
