My salmon faverolle has been staying at roost longer than the others and is fluffed and sitting around when she is out and about. She is eating and drinking. I can't figure out what's wrong with her. Do hens get lethargic in winter? In a first timer. Feet look good. She has laid a few eggs, but hasn't laid any in almost two weeks, shorter days I think. Crop empty this morning, full last night. Vent seems closed fairly tight, and I don't feel any bulges. No drainage from eyes or nares. No strange neurological symptoms. What could be wrong? She's definitely gotten worse the last couple of days.
