Botched Chicken Introduction - what now?

[Magelet]

3 weeks ago, on short notice a friend of mine had to rehome her 5 two year old chickens. I had only 2 chickens also both about 2 years old and a setup that was made for 6 and I thought could handle 7 so I said I'd take them.

We introduced them in the coop at night. There hasn't been a lot of fighting, and no one is being picked on, but my two girls are mostly avoiding the new girls. To the point where they don't sleep in the coop. I have tried shutting them in the coop overnight multiple times but that is the only way to get them to sleep there. My Buff Orpington would prefer to sleep on top of the coop (it is sheltered by the overhanging roof of my garage) and my silkie would prefer to sleep in the bonus hutch that is in the enclosure that is for when we put the bunny out there in the day. Winter is coming on and neither of these seems adequate shelter for winter. What do I do? I would rather rehome some of the girls than have to go out there every morning and evening to shut them in (the coop has a flap like a dog house that has worked for years because my chickens have WANTED to go in at night). Attaching pictures of my setup.

Whew, from the pictures, I’d say that coop might be big enough for three, but not for 6. (Or 7.) What’s the square footage, not counting the nest boxes? How long is the roost that they sleep on?
