The frame is not from our view. It is from that of this singular chicken who has only ever known its keeper's care. As that chicken, we simply do not know if Christmas will ever come.

The collapse of civilizations has happened many times. Today, all of humanity is bound tighter than ever before. In the latter half of the last century, we were on the brink of nuclear war.

New things are happening under the sun every day. If we were that exceptionally smart chicken you describe, then we have reason to expect Christmas.
