Wire looks good, can't tell how it's attached tho...also can't tell how latch on nest box operates, if it's raccoon proof.
Apron good idea. Do you lock pop door at night?
Any predator hungry enough will attack during the day.
I used 2x4 welded wire with apron for my run.....but I am home all day, often in sight of run.
It's not totally secure, except against hawks, but should slow anything else down considerably.
