Hi guys, I've got aboutique a 5 week old duck and it's making a sort of soft coughing sound. It's been acting totally normal, kept in a warm area with a heat lamp that they can get away from if they're too warm. I've also been giving them a warm bath every day, mostly just to let them play in the water every day, but also to keep them clean. Today the one started making a soft coughing noise that or a huffing noise? Like it's clearing it's throat? I checked to make sure there was nothing blocking it's airway anfor they always have access to water and there's no discharge from its nose so I'm not sure why it's coughing. Anybody have any suggestions?
