Welcome! 8yrs old? That's awesome!!!
I think it is a possibility. Just take care of her - if she's in 80 degrees F, no shade, that's not healthy. They don't always choose the healthiest or most convenient sites - a sitting duck is just that - very vulnerable, and steps need to be taken so she will be okay.
I am the new one to this forum. I just figured out how to post a picture.... This pic is a couple of years old. The 2 swedish ducks are now much whiter as they turn get whiter with every molt. They are 8 years old, but they still lay eggs about 6 months out of the year. I love them and have enjoyed reading this thread and looking at the other pictures.
