When I built my first coop I didn't give a lot of thought to predators. Ater losing 5 hens and 3 roosters to raccoons I decided it was time for some reinforcment. This is the coop as it was originally built. Now with heavier gauge wire and totally enclosed the coons can do nothing more than stand outside looking in. A little bit of extra time and money will go a long way to protect your flock. I learned that the hard way.
