Hello, one of my 2-year-old buff orpingtons has a large fluid-filled mass below her vent. She’s still free ranging, eating and drinking (as far as I can tell), moving and socializing normally, and her comb looks firm and red. Last night I gave her an epsom salt bath and sprayed vetericin on it and offered probiotics in her water. (It’s all I had in hand.) I couldn’t feel an egg when I checked. Is there anything I can do for her? Any chance she’ll be ok?
