8 yr old Pekin Died two days ago, I’m worried about my female

[BA-DuckMom]

Sorry for your loss

I doubt that black/greenish poop was abnormal. He had probably been eating weeds.

It's hard to know what happened. Tell us more about his death. Did he just collapse and die suddenly, or were there any other symptoms that morning or before he died?

Many pekins live only around 8-10 years as they have been bred over thousands of years for rapid growth and culling for meat at only a few months old.

I would not give you duck ivermectin. It's intended to treat intestinal worms. A photograph of her poop would be helpful

I failed to tell that she is an indoor duck. They both were. I had no idea what I got into when I took on these two. I’m better for carrying for them but I never could afford the kind of really good shelter they needed for the winter. We have huge hawks and coyotes. I put them out in the summer during the day and kennel them at night.
