I have heard of ducks living 10 years or more so you may want to check on your baby as she may not be feeling well.
I agree with the checking up on your duck because panting is not a good sign. The average, from what I've known, is about 7 to 8 years lifespan. If it's a jumbo Pekin, it might be a little shorter.
