So, we have a pen full of chickens to get eggs from. This was before the hot and cold variant chickens were added. We slept in our beds and then went into the coop to gather the eggs the next morning. We noticed the baby zombie riding on one of the chickens. We didn't know that could happen. I looked it up and only found out last night that it was a chicken jockey and that they were rare to spawn at all. Just thought I would share.
