That must have been very scaryShe was lucky I'm a light sleeper. In the wild, she'd have been fox dinner.
I was dreaming and thought where's that chicken? Can't see it anywhere. There's a chicken around here somewhere. There it goes again *Awakens* THAT'S ONE OF THE HENS! SOUNDS LIKE MARY! And I was off and running.

I wonder how she managed to fall and get stuck. Do you need to remove the sawhorse ? Even though it was certainly a one shot event I would sleep with one eye open tonight.
My hens fall very often now and don't seem the worse for it. The setting (which we didn't change, it's at least 50 years old) required pretty good agility and as they get older and especially during molting it's difficult for them to roost and access the nests. They could switch to lower roosts and nests, but they won't. They fall and try again.
