I've had two chickens since day one and they've been together inseparable ever since. I came home today and one was missing, literally gone from the face of the earth it was so hard looking for it cause I couldn't stop from getting teary eyed. I have NO idea where it went. I looked for HOURS. We have an enclosed back yard. I looked around the perimeter, we thought a cat or another animal took it but we see no feathers or blood. The other chicken was by herself roosting in a corner in the garage sort of scared.....we think someone took the other chicken while we were away. So I was wondering...can the lonely chicken die of loneliness? If they do...what are the chances? My mom thinks it might. Thank you.
