Can you keep them in their hut for a couple days so that they "get it". Then let them out to see if they'll go back in by themselves...I had to do that with my chickens a couple times....dang birds wanted to roost in the woods BEHIND the coop. I even had one rooster that wanted to roost on top of the coop. 

She was not that stiff so I say sometime last night. She had no visible issues. Just looked like she croaked and fell into the pine shavings. 
I hope she does come by.
