Hen not going in at night

[BDutch]

There are two. They're closed for the winter because they're near roost height. They get air circulation through the eaves and the small gaps I left when constructing the nests.

I meant a real glass / perspex window , at least in winter.

Any other ideas to ease her back into sleeping in the coop at night during the upcoming weeks of cold weather are welcome as well.

Maybe something over her head?. Like a tiny tarp. To feel more safe.
