Also left the door to the sexlink coop open by accident a few days ago. Something snagged Mrs. Reynolds that night. I still haven't found any remains, so I really don't know what it would have been since odds were something would have had to climb/fly into the top door down into the box and then take her out. Screams raccoon to me, but they never moved birds very far last year and nothing has come back so far, thankfully, so I'm hoping it was just an owl or coyote that snagged her on a lucky break. More than possible if she was sleeping on top of the run and not in the house.
They might have tried to snag the Wyandotte too, a lot of her feathers were in the house, and she suddenly looks like she's in the middle of a hard molt.
Tying the door shut for now, just to discourage anything that might try again.
