This came out of a hen who has been acting fine until this morning. She did not want to come out of her coop or off her roost. I nudged her a bit and about a minute later she came down on her own. But she had some whitish yellow paste on her butt. I took her in gave her an epsom salts bath,fungal spray on her vent, ACV, epsom salts flush, and plain Greek yogurt. About 45 minutes later she passed the membrane looking thing. It is completely translucent, only clear liguid inside, does not seem like a tapeworm and so on. Also she stopped laying March 5th about 3 days after she lost a flock member which was her original flock member. Once she passed membrane she perked up and free ranges all day. She was a bit more tired than normal, but eating and drinking.
