How would you make this opening predator proof?

That`s a ton of them to worry about!

Competition for food is fierce in the desert. Everything wants a chicken dinner, or at least their eggs.

Alternatively, though not a desirable option, you could forget that door (cover it completely) and build your own secure door on the opposite side
Or build a double gate (think "dog park". Gate, containment area, second gate.)

I'm not sure how it'll fare with predators and winds, though
Looks like you aren't prone to snow/freezing, so that's good? I've known of those buckling in relatively light winters.

We sometimes get a light snow once or twice a year. We can get tornados. A tornado touched down not too far from here but we got the wind. It destroyed one of our earlier runs (we saved the hens by standing out in the storm and holding onto the coop for dear life).

A secure door brings me back to this. We'd have to build a wooden frame for it and it would sit against the door opening on the outside.
