I'd add some harware cloth to that run. Looks like you have 2x4 welded wire. To easy for critters to get through or reach through. A three foot barrier of harware cloth would be good insurance. I love the storm door!
Are you planning on painting it? It is best to do so to help the OSB last longer. I would also be sure to have a second lock on the screen door as those rascally raccoons are clever (and strong!). If you lock your birds in at night and when you are not home your fencing is fine (with the bottom reinforced) but if not then you'll definitely need to reinforce the run including adding 1/2 hardware cloth the first few feet to prevent raccoons grabbing through the larger openings of your current fencing and add electric hot wires near the ground and near the top of the fence. It is also to keep out loose dogs who get a whiff of chicken and think of a nice snack.
Its a great to see you have netting on the top to prevent raptor air strikes. Looks like you have ventilation near the roof too
Its tough to tell if you have any protection along the bottom of the fence yet. If not, any critter can get in even if your birds cannot get out. It takes so much thought into making it predator proof--as well as expense and time.
Really nice start--can't wait for the final photos!
