Need help deciding what to do with this coop

[zonamiss]

Ok the home we moved into had this coop that was used at one point. I'm not sure how long it's been unused but you will see from the pics it's been a while. Where do I start with the rebuild? I know the run outside needs to be rescreened which makes me want to widen it a bit. But the inside omg it smells. It smells it smells. I just want to cry. How could anyone keep their chickens in this horrible condition? No roost or anything.

I've seen things like that.
You just need to muck it out and clean it within an inch of its life. Make sure you use a dust mask as you work.
I'd scrub down all the inside, hose down or vacuum everywhere there are cobwebs and dust.
Once it dries out, paint it so it's easier to clean in the future.

I would add some ventilation at least.
