She's had an anti toxin she doesn't need a flush but thank you for the suggestion. I do have her on electrolyte and vitamin fortified water to keep her hydrated. mostly she's sitting in the dark and quiet to reduce stress. She's a wild duck so the best thing I can do is make sure she doesn't starve or dehydrate while she recovers.
Do you have any idea what she ate? Are you a water fowl rehabber?
