My 3 year-old hen was fine Sunday, then began sitting alone with her feathers fluffed out Monday. I brought her into the house and noticed a lot of poop around her vent, so I bathed her and kept her in a crate over night. She was eating and drinking fine at that time. She has steadily declined and at this point, hasn’t eaten for 3 days, won’t stand, sleeps nonstop, and won’t drink unless I make her. I’ve her in Epsom salts nightly, given her electrolytes, and poultry NutriDrench. She will not eat. She never pooped Monday, but did Tuesday in the bath (very foul smell), twice yesterday in her crate, and once today. During her bath tonight, I noticed some goo coming from her vent and something small that appeared to be white/black and chunky in what I assume is her sphincter. When I lightly touched it, she groaned and appeared to be in pain. I’ve attached a picture of her vent area (though what I described is no longer visible). I’m not holding out much hope for her recovery, but want to do all I can for her. Advice requested, please....
