So I've read multiple forums about a change in a duck's quack, but I haven't found anything similar to my situation. I have three Khaki Campbells that are very bold and two dogs that don't have any interest in the ducks whatsoever. Yesterday I gave the dogs their food outside, and the ducks went to go check out what was going on. I knew I should have just brought the dogs inside, but shoulda, coulda, woulda. One of my dogs was eating and the ducks walked over, and when one of them got too close, the dog bit her. I check, double checked, and triple checked and I can't see any blood or any sign of physical injury. But now my duck, the one that was always the loudest, is quacking quietly and very raspy. It sounds like when someone breathes out of their nose loudly. And one of the ducks, and even the dog that DIDNT bite her, have started to chase her. It's like they see something about her that I don't. She's acting completely fine otherwise. I have separated her just to reduce her stress, and currently have her in a warm bath with a little ACV and her favorite greens. She's still acting completely normal, eating and drinking like a maniac, and she's even quietly chatting to herself like normal-- it just sounds muted now. Anyone else have any suggestions for what's going on or any treatment ideas?
