Dead hens

[tipsy terry]

For the past week, my girls have been in their coop at night secure. I go out there and every morning there is one dead hen in the coop. There is no show of any predator getting in. Is it possible? I have a rogue hen that is killing my hens

Can you get a camera in there?
If a chicken killed a chicken, there'd be a mess.

Do the dead hens look wounded, bloody? Or just dead on the floor?

Have you checked all of them for signs of illness (mites/lice, sneezing/coughing, eye or nose discharge)? Do they have access to a compost pile or moldy feed?
