You might want to consider not having eggs in the slots right by the turner motor. I've heard it can get overheated from the heat of the motor. Or at least swap that egg with another each day so no egg spends too much time there. Some turners even have a blank spot there so it can't be used.
But I suppose everyone's experience varies.
Good luck with your hatch,
