My duck has bright yellow skin

[Duckmomof6]

My duck, Charlie, has bright yellow skin mainly on the left side of her hiney. Her tummy is swollen like she needs to ve drained.
Charlie does have cancer in her uterus. She had surgery in January to confirm, and she just recently had bloodwork. Has anyone seen yellow skin on their duck?

Do you feed any corn?

Do you feed any corn?

I do. She loves all veggies

Corn can sometimes leave fat deposits below the skin. That's what I was told when I asked about random yellow splotches on some of my birds skin. I'm not positive that's what you are seeing on your duck. Just a possible cause.
