Before starting, the photo below is obviously gross. We're new chicken owners and have recently had problems with our oldest hen (approximately 15 weeks old). We're having a difficult time figuring out if she has a case of Vent Gleet or if she has a prolapsed vent (or something else we don't know about). During the first few days of treatment she was acting "sick"- she was lethargic, tired, not active, but she has improved to about 90% of her original self in the days following. We've been treating her as if it's Vent Gleet for the last week but have not seen any improvement (but it also hasn't gotten any worse). We have been treating her for the past week with apple cider vinegar water (with Mother), soaking her in a tub of warm water, giving her plain yogurt (sometimes with chopped garlic mixed in), wiping/cleaning the vent multiple times a day and applying Tinactin (anti-fungal ointment). A few days ago we stumbled upon prolapsed vent and thought that maybe we misdiagnosed her. We switched her to PreporationH ointment as we read that helps reduce the swelling of the vent. Is anyone certain as to what this is? And, how to treat it other than the steps we have been taking for the past week. Thanks!!
