Lots of potential there, nice big space.
Most my thoughts have already been expressed by other posters.
I'd get rid of the concrete in the run area....and of course add mesh against predators.
1/2" hardware cloth on any opening/gap larger than 3/4" in coop.
Anti-dig aprons all around...maybe even on coop/barn wall.
Top hinged windows in the coop for light in winter and extra ventilation in the summer would be good
Keep in mind that if you open 'big windows' into the barn you'll likely get a lot of 'chicken dust' in the barn.
Might be good to put nests in/on the coop/barn wall so you can gather eggs without having to go into the coop.
