I went out for the final check on the animals. I could hear one of my call ducks with a raspy breathing. I have isolated her in the house after giving her a good bath. Question is, what do I give her to get her over this. I have read you are not to give them medicated feed so what kind of medication can you give them and how much. She is a butterscotch call duck. 1 year old. I have a feeling with this cold weather we might have more of this. Please help.
