Very strange death, Please reply ASAP

[The Duck Ladie]

Sounds like a weasel or mink

What is your pen made of fencing etc and is the top covered?

I don't have a covering, I'm afraid. The fencing is high. It's a dog run and panels with chicken wire on them.

Hello...The puncture wounds were from that dog attack I'm pretty sure and the Duck died from internal injuries that took that long for her to succumb to them...No weasel...
