Silkie hen with green mold on butt died suddenly

[The Birb King]

So I noticed my only silkie had a very dirty butt so I wanted to clean her up a bit. When I cut away some of the poopy feathers, I noticed this green flakey stuff around the vent that kinda looked like mold. Then when I was almost done cleaning her up, she started moving around a lot and appeared to be struggling to breath. When I put her down however she started flailing around like she was having a seizure or something then a few seconds later she just stopped moving and died. Anyone know what could've been the problem? I have never seen anything like it. It was very weird.

I'm sorry about your hen

Without necropsy it would be hard to know what was ailing her. Do you still have the body so you can send it to your state lab? https://www.metzerfarms.com/poultry-labs.html

I already buried her, so that would be kinda hard to do at this point.

Great advice! This is a classic situation where I’d send a bird out for Necropsy; my worry for the other birds would be my 1st reason to get one, while my curiosity being a true 2nd as I’d go silly not knowing exactly what went wrong …
