Hello! I need some help regarding waterfowl. I've wanted to own ducks or goslings for a very long time, so I made the necessary arrangements to have some. A few weeks ago, I purchased a duckling. Very suddenly the duckling passed from what seemed to be a respiratory infection, or pneumonia. I was so sad, because I was really starting to fall in love. Well, I went to go get a gosling after cleaning the house thoroughly in case there was a potential bacteria that caused the duckling's death. Now I'm very worried that the gosling is going to suffer the same fate. He's been sneezing more frequently, and has watery stools. My chickens have been unaffected, and are thriving. I have penicillin but I'm at a loss. Does anyone have any advice? Is there anything I can do before it is too late?
