I took her to the vet when I noticed her breast meat disappeared but her weight stayed the same. They did a fecal test and found cocci and whipworm - we did treatment and I took feces back and cocci was down to 1 (from 2-4) and whipworms were gone. She is getting more bloated; her barely any mass in feces/green/liquidy never changed either. He's not a chicken vet, aren't any. Still $130 and she is no better for it. Now the fluid is getting so profound her belly is bigger and she sounds like she's getting a respiratory rattle. My other hen who did this we culled in July after giving her bath and finding a huge hole in her under her vent filled with maggots. This must be some kind of gut rot that antibiotics only make worse. Anyone have a clue?????
