Not A Single Mark On Her!

[newchickmom]

I just got home from work and found 1 of my BO hens in the run, Dead!
I felt her crop and checked her for prolapse and egg binding, and Nothing!
What could have killed her and not left a mark?
All were fine this morning when I went to work. I open the pop-hole door before I leave and it is still dark now.
Any ideas?
I also have a kitten missing, so I'm thinking I have some sort of predator around.

How old was your hen? Maybe she died of natural causes or something could of scared her to death?

She was only 6 months old.
