Raccoon proof

[AShelDuck1]

We repurposed this shed into a duck house and chicken coop.

Currently we have new chicks and ducklings brooding in there.

The adults of my flock don't come in at night. Should I make them?

But main question how do I make these doors more raccoon proof?

My run is so big I don't think it's possible to make the whole run raccoon proof.

Hardware cloth on the wire door would add security.

What kind of ventilation do you have for the coop (not showing in pics)? Hardware cloth should be used there as well.
