My chicken died and I can't figure out why. She was just found laying dead in the coop. No missing parts, no pecking, nothing. She was less than a year old....about 9 months. I have them all living in a greenhouse with electric netting around it. I wasn't home at the time she died, so I had my sister put her in the freezer so I can examine her. Today when I was looking around at the back of the greehouse, I noticed a hole tunneled under the back of the greenhouse and it comes through to the front. Small hole...probably an inch or so in diameter. Could this be related, and what kind of animal tunnels right next to an electric fence?? The hole starts inside the electric fence, so it would have to be something that came through the electric fence...maybe? I don't know. I'm confused about this death.
