Others have answered on ventilation. I agree, its not enough. I'm going to offer different advice. Remove your metal panel roof.
Its not attached correctly anyways. Placing screws in the crown of the profile will cause long term problems, its bad practice. Set some lumber on top of the existing house, on edge, reattach your roof to those. If you use 2x4s on edge, you add 3.5" of height - that's almost 1/3 sq ft per linear foot of roof line, and you get it on two sides - so if your coop is 6' wide, you've added ventilation for four birds. 2x6s are 5.5" "tall", almost 1/2 sq ft per linear...
Then firmly attach some 1/2" hardware cloth (screws and washers) or big poultry staples (1 1/2"+) to cover those new openings you've created as small climbing predator deterrence. Unfortunately, you don't appear to have much roof overhang to play with, you should consider adding something to deflect rainfall blown at an angle which might then enter the ventilation. Even hanging a cheap plastic gutter would give a few more inches of overhang - all you need - just extend it well past the side of the coop, so it deposits water in a low spot away from coop, directed out of the run.
