I have a very sick hen and my research and vet back and forth hasn't helped with what to do. An older hen started to sleep a lot about a week-14d ago. Truthfully, because of her age, I thought it maybe was her time. Picked her up, looked at her, didn't see anything obvious. Does seem to be eating and drinking from what I can tell. Doesn't appear to have lost weight. Crop is not full. I've been looking at her and picking her up every few days to see how her weight felt. Yesterday, I noticed an odor and sticky stuff on her mouth. Smelled her and it smells bad, but not awful. Opened her mouth today, and she has little white spots on the top of her mouth and a wad of white gunk in her throat. It looks like the worst sore throat ever. I can tell she's miserable, but I can't figure out what to do. Swab it and determine what sort of bacteria is getting her? Could it be fungal? I'm willing to take her to the vet if needed. My primary isn't really avian though.
