As for your question re temperatures: I do not think I would bring them in my house! Simply be sure they have a dry coop that is draft free.
To help them to re-grow their feathers you can give them more protein. Can you buy a (not medicated) feed that is 18 - 20% protein there in Belgium? If that is not an option, perhaps you can give them some animal protein, even some eggs, or a bit of cat food (short term)
I wish you the best with your efforts.
