Very sick duck. Help and opinions please.

Well, Peggy was outside for over 3 weeks. She was eating happily and able to walk, nothing like when I brought her in the house. You could tell though, that she just wasn't herself. One day she looked terrible, sunken eyes and all fluffed up. The next morning she seemed ok. Then a couple of days later, I went down to put them to bed and she had died sometime in the day. I only wish I knew why she got sick to prevent it from happening again (if indeed it was something that even was preventable). I miss you my sweet girl.

How sad...
