How enclosed does the coop have to be from the run?

I hope this makes sense... I can add pictures later to explain more
Basically I'm working on building a coop. So far we have a frame with a roof and one one wall that has nesting boxes built in.
We are working on covering the remaining three walls.
We had an idea to cover the half of the coop with the nesting boxes with wood (solid cover) and the other half with chicken wire, but no barrier in between.
So it would be half run/half coop.
Would this leave the chickens too exposed at nighttime?

Here's mine, it will need to be predator proof.

Wow, your coop is pretty deluxe... and also looks much bigger and more enclosed from the run than what I'm talking about.
Our coop should still be predator proof, but at night they won't have full solid walls on all 4 sides. One end will just be chicken wire on a frame.

Thanks for the response

chicken wire keeps chickens in but nothing else out-

use hardware cloth if at all possible.
