A direct attack on a single hag seems to be the best option that I can see. Hags try and use ambush and sneak tactics to catch the party off guard. Possibly tricking the players to split up and attacking them one by one. So, if I new the hag was a hag I would attack with my most powerful attack. Trying to do as much damage as possible quickly.
