Duck sudden paralysis and death

[Pollo Blanco]

Oh no. I know you're not supposed to give them avocado but I didn't know it could actually kill them .

Doesn't every time. There's some chemical that acts to prevent attack by tropical rot in avocado and it's quantity dependent.

I also thought maybe it was lead poisoning and she had eaten some BB pellets, as my brother had been shooting some in the area. I checked the container and they are steel with zinc coating, but they do say "this product can expose you to lead" on the back.

Check out zinc toxicosis. Could she have eaten a lot of pellets or been eating them for a long period of time?

It sounds possible. I don't know how many she would have had to eat for it to result in such sudden death. There have been pellets in the area for at least a few weeks, though I don't really know how many.
