How long do I have too hatch an egg before the game says my egg is getting too cool to hatch? I have a sonic egg ready to hatch, but my air habit is full and my lightning habitat will not upgrade  for 15 hours without a gem speed up. Will my sonic egg last for 15 hours before it is too cool/ cold to hatch?
