Emergency Rooms, also known as ERs, are hatcheries or sections of hatcheries exclusively for dying eggs and hatchlings, who depend on clicks to help them hatch or grow up. Emergency Rooms come in handy when an egg or hatchling is required to hatch or grow up in a short period of time. Different sites have different 'Magic Numbers' for emergency dragons. However these are typically between 3 and 4 days remaining. A dragon at or below such number of days will be recognized as an emergency and the player will be able to add their dragon to a site's ER.
