Hi everyone!
This morning my dog was along side my bed winning at me to get up and follow her. So as I started to wake up she barked from the bedroom at something. I thought oh crap that's not good and grabbed my gun. I went to the sliding glass door and Momo my dog was growling. I slowly opened the shades to see what it was. There were two raccoons on my porch and two more in the yard. So I opened the door and made a hissing noise and the two farther away climbed up and over the 6 foot wood fence and high tailed it out of there. The two on the porch were really brave as they stood their ground. At this point Momo (half shitzu and bischon) finally got up the nerve to stand out side the dog door barking. At this point the barking was enough for the coons to scatter up the near by tree and I went to get my pellet gun to scare them off. When I came back they had run off but it left me concerned about the security of my chickens. Living in a residential area I had seen deer that come in from the fields and smell a skunk regularly but this is the first time I had seen a raccoon let alone 4. Which leads me to conclude they were trying to make a meal of my birds. First I need to latch the nest box door. Second I need to buy some carabiners to keep the coons from opening the latches. My concern lies with the chicken wire on the run. The raccoons can reach through and grab a hold of the chickens right? Should I put up 1/2" square mesh around the lower half to prevent this? Or are they safe in there? Below is a pic of the coop. The chicken wire extends outward from the bottom about 10" to deter diggers...
