The best protection is to be able to close your birds in their coop at night as many of the predators roam at night. Of course there are a few exceptions such as hawks. I was loosing birds about every other night out of a couple of my pens and I have electric around them all. I couldn't figure what was killing them so I put my gamer camera out and found out it was an owl. I have since put netting over the pens and haven't lost another bird so far. Each coop we have we built, and all are different. We have 8 coops. 2 of the coops are duplexes so we can separate birds or open the gate and use them as single coops.

We have added 2 more coops since this picture was taken.
