Well there you go... firstly, many chickens really prefer to roost "al fresco", so you are automatically working against that; and secondly, they may have trouble seeing to get UP to the roost or may be getting chased off by the other chickens (not uncommon Polish problem)
I don't know how well ventilated or well-windowed your coop is, since I can't see the whole thing, but unless the parts that aren't shown are *greatly* different from what is shown, I would suggest that adding a big ol' window and buncha extra ventilation might help. Possibly also a secondary roost, at a lower level. And then manually put the polish in there every evening til they clue in.
It is really much much safer for the chickens to have the popdoor closed at night. Chickenwire DOES NOT keep out predators. I would hate for you to go out there one morning and find piles of bloody feathers. Closing the popdoor would automatically solve the roosting-in-opening problem.
Best of luck,
Pat
