It looks like one of my ducklings, the Pekin, is panting a lot lately. In situations where I am pretty sure he cannot be overheating. It looks just like it's panting. It's bill opens and he moves it up and down just like I have always seen my ducks do when they get too hot, except that the temperature is around 70 and their light is not on. Any other reason a duckling would pant?? Georgie is about 5 weeks old.
