Help! My girl Goose is looking extra puffy and has this weird discharge on her bum. I’ve tried a few things with no change. She’s lethargic and not eating or drinking much. She randomly laid 2 eggs then stopped. She wasn’t laying all winter before this. There are no lice or mites on her. She’s around 5 (we think). I’m not sure if this is a parasite or something else.
