I have a coop that sits on the ground but has fencing attached to the bottom as flooring. I then put a 2" layer of pine shavings on top of the fencing, and that is where I keep my 4 turkeys. One of the hens just started laying eggs about 3 weeks ago. Shortly after I noticed holes around the outside of the coop. This morning when I opened the door there was a tunnel that was dug under the door and the opening was inside of the coop with lots of fresh dirt spread out everywhere inside, like it was digging back out of the coop. The hole is a little larger than a one dollar coin. I thought maybe a snake at first but now that I saw all of the dirt sprayed everywhere inside I know it has to be a furry little critter. Anyone have any idea of what this may be?
