Well..... for the first time since I built the coop/run I have lost a silkie to a raccoon. Hubby's favorite splash too. We didn't build Fort Knox and knew this was a possibility. So we aren't that upset. But it wasn't easy for the little demon to get in though! He had to dig through packed dirt, that normally takes a good watering just to get a shovel into, so that he could get into my yard to begin with. This is a feat unto itself because my dogs have trouble doing it. Then we found no less than 5 spots where he had tried to get into the main run, again through that same packed dirt and down 6" where the lumber was dug down to, he couldn't get that far through the dirt. Where he got in was right at the front door where we had dug out a pit to help with drainage and shoveled back in about 10" of heavy road base type granite gravel, all the way to the bottom of the door. We top this off as it packs together but apparently he was able to dig right through it, though it didn't look easy. Once he was done with his massacre it looks like he had trouble getting back out because there were several places where it looked like he tried to dig back through that packed dirt and couldn't get very far. The complex has been there for a year so it's a bit strange for the demon to wait until we are about ready to move before making an attempt at this. For today though, it's fix the perimeter to save what's left until I can get packed and move.
