Hi, I have one hen that has had a fluid filled abdomen on and off this whole summer. DLHUnicorn told me about using brewers yeast for this problem. I started poking a brewers yeast down Tulip's throat each day for about 2 weeks (it took a while almost all summer) and the fluid is gone. I read that this fluid build up (ascites) can be caused by high altitudes. Are you in the mountains? I am here. It took several months of giving her this pill and now I just give it to her about once a week for maintenance. I don't know if it was because of the pill or if it was a coincidence but......it is gone. I never did aspirate the fluid. Don't know if you are having the same problem but it might be worth a try. Good luck with her and happy holidays.
