Are you interested mainly in regular hexagons where all the sides and angles are supposed to be the same?
Here is a link to a TechNote that describes one way to check octagons, and it might be easily adaptable for hexagons. For instance, instead of checking the angles for 135 degrees, you could change the number to 120 degrees. And instead of checking the number of sides for 8, you could change that number to 6.
Watch out for hexagons that are so close to each other that their extents would overlap. That might not be handled so well in the example above. A different approach might be needed. Would you let us all know if it works or if you find something better?
