Chicken bald back

[Janepie33]

One of our girls has decided to sleep outside in sub zero temperatures!

She goes to bed at dusk with the other 5 girls, but at about 11 pm, she comes outside to roost on a branch in the walk in run. I've no idea if she stays out all night, but in the morning she is quite happily pottering round with the other girls. She is also laying regularly. She is very near the top (if not top) of the pecking order, so I don't think she has been turfed out by the other girls.

Has anyone any idea why she might be doing this?

Henopause? Probably gets hot flushes like a lot of us girls. Can't fling her feather duvet off so does next best thing. Obviously not bothered by the cold.
