Protect bald spots in extreme cold conditions?

[Pullety]

I have a hen who has started moulting with the coldest temperatures in years about to arrive - forecast -37C. She has a couple of bare patches on her head and her back. Should I try to cover them somehow to prevent frostbite? What can I do?

I let hens like this get into my heated nest boxes at night. They get out during the day and spend most of the day hunkered down in the fluffy dry bedding in the coop to stay warm and do fine.
You could provide a huddle box for her and put it on the floor of the coop with lots of thick dry bedding in and around the box. A huddle box is just a box laid on it's side to form a little cave. She will want to roost with the other birds so you would have to move her after dark to the huddle box.

Thank you so much for your reply. I made her a cuddle box and snuck her off the roost. She didn’t want to be in despite my trying. So I stuck her between two roos. It looks like that created enough warm air over her bald back.
